I have never seen those amps before. They look like they could be a lot of fun. Wow. A little too rich for my blood at the moment unfortunately.
-
Listen to what this guy is saying. I bought a Dynaco ST-70. Fantastic, wonderful amp. Now, after an additional $1K that I put into it replacing old parts. I thought I was getting a deal on a $300 amplifier but these old amps always have something that needs to be replaced. Unless you can solder think buying new. There are plenty of options in the under $1,000 range that should suffice. If you can't solder you can still buy used equipment that is just a few years old that you can ship to a tech but vintage is a whole nother animal. But if you can solder, or have someone around who can help you figure it out, the best deals are easily in vintage and kit equipment.

My Dynaco came with some well used Tesla El34 tubes. I have bought many others since then and the only ones that compared were the JJ KT77. If I had the cash, and if I were still using my Dynaco (I may go back, that remains to be seen) old stock Tesla is definitely what I would purchase. Failing that the KT77 tubes seemed like an incredible value. I can't compare them to Mullard but I remember the Tesla being incredible.

I am actually a little bitter over his contentment, have so little contentment myself. Ack!
-
Color me surprised but given the effeciency of the Heresys 2 watts should be enough to push them to ear drubbing levels much less 6v6 in a push pull configuration. Something is going on here and it is not the theoretical power of the amplifier which should be around 15 watts. It is either not pushing out enough juice because something is wrong or there is something else in the chain that is screwed up.
-
Interesting thing is I have my amps going into my Chorus II and have
too much bass. And when I played 2 watts into Mark's Khorns I
didn't notice any bass was lacking. I wonder if auditioning
another SET amp is in order. Wish you were nearby, I would bring
mine over.A powered sub is always an option.
-
What does a pair cost?
-
Though I suppose if I have to $200 may not be reasonable.
-
Ok, thinking it over I may decide to buy an aftermarket crossover and
skip the whole nightmare of figuring out what to do myself.
Thinking $200 max and thinking it will have to be a Christmas
present. But might as well start researching. I would like
to know what is available and what is involved. We posted about
this before but I can't find the darn posts. What caps are being
used, do we reuse the iron that is in the current crossover or replace,
is it a redesigned crossover or better parts...? Would like to
get a feel for what my options are. I think Chris and Dean are
the two options, correct?
-
It does help and I appreciate it. I haven't done a crossover
though I have built multiple amps and preamps. I will also have
an electrical engineer here to help me out with the build who has been
doing this sort of thing for 30 years. I will forward what you
have written to him and then decide if it is really something I want to
tackle. I will let you know if I decide not to rick screwing it
up as I want to improve the sound not break my new speakers.
-
I have decided to go ahead and move the
crossover onto an outboard crossover and put in new capacitors. For the moment I am going to just use Solen
and try boutique caps later. I will use screw down terminals so I can swap capacitors in and out. But I
wanted to check some things. How hard
is it to get the crossover out? Apparently it is inside the speaker on the back of the piece with
the speaker terminals. I can see that I
can just unscrew it but is the piece of metal glued to the speaker or does it
just come out? Am I going to damage
anything when removing it? How hard is
it to get the other items off of the actual crossover that I want to save such
as the transformer, inductors, etc Those appear
to be glued on from the picture I have seen and I dont want to replace those if I can save them but wonder
how much heat I need to put into it to get the glue to liquefy. Anyone who has done this with a Chorus or
Forte I would appreciate some pointers before I destroy anything.
-
ooh! ooh! Look at the pretty McInstoshs'! Very nice.
-
is simply to swap it to another position, preferably on the other
channel. If the glow follows the tube you've got a bad
tube. If the other tube glows in the socket where the tube is now
glowing it is the amp and trouble shooting begins.
-
Bottlehead Foreplay III and a Seduction might work. They are
seperates but about as good as it gets for the money IMO and close to
your budget.
-
I already have 10 with my Bottlehead preamp and Stereo 70. The Bottlehead
300B Paramount amp I have coming uses expensive tubes. I didn't want more
variables, added expense, and I didn't feel like I wanted to deal with
more tube rolling so I steared away from a tube dac and tubed phono
preamp. I just didn't want to deal with the search for the right
tube and all the worry about the sound quality variables inherent in
tubes beyond my amp and preamp.
-
Budd of mine who sold audio gear used to say that a turntable sounds
95% like its needle. I bought a cheap(er) turntable and spent
more on the needle. I think the advice of sticking with this
turntable for now and getting a new needle is sound. Might want
to spend a bit more on it though. And if he can find a local
dealer who sells needles they should have no problem with him bringing
his turntable in and putting it on for him. Next step is the
vacuum record cleaner! That will make a huge difference. -
Doing the speakers first and then the amplifier is the right way to
go about it. There have got to be some people near you with a
300B amplifier that would either bring them to you or let you bring
your speakers to them. You can post at the following websites and
ask and see what happens. I don't know if Wright has a forum.http://www.audioasylum.com/forums/set/bbs.html

And I am sure there are others.

We have only heard two watts coming out of a 6DN7 tube on the
Klipsch. I have listened to various amps and speakers but haven't
listened to too many amps on Klipsch other than our various iterations
of the Dynaco and the S.E.X. amp. When I get my Paramounts maybe
another trip is in order to listen to 8-9 watts on some 300B's which is
a whole nother animal? It may be a while with the school year
keeping me busy but it is something to think about. -
Being able to switch between amps is a pretty nice idea, I wonder ho
hard that would be to implement in a Bottlehead Foreplay. There
are times I bet that I wish I could switch over to push-pull but won't
bother. I actually agonized over the decision wondering if I was
spending money needlessly I love my Dynaco so much.After I get some time with the Paramounts I will post what I think.
-
I really am looking forward to getting my own 300B amplifier.
-
Great. And I understand that you have nothing but positive things
to say about their service. And I have never dealt with them just
read posts. That should be taken into account.
-
Color me embarassed. I thought you were referring to the Moth
Cicada and I couldn't understand how three watts would clip with
it. I get it now. I also have a Dynaco that I am also
running into my Chorus II (25 watts) with very satisfactory results and
have been happy with the increased authority of that topology for years
though I have been going another direction lately, sometimes I wonder
if I am not doing for the sheer joy of something new. There are a
lot of intelligent people that will make an argument for SET,
Push-Pull, or solid state as the case may be based upon the strengths
of those mediums and their own preferences. I don't think I am
locked in any way (I hope). The funny thing I find is the most
vehement and dismissive, to me at least, seem to be the solid state
guys (some). The SET guys usually admit SET's faults (when is the
last time you heard a SET guy tell you that the bass of a SET amplifier
can't be beat?) and recognize the strengths of the other topologies,
they just know what they like best. The original post was about
what SET amp might work so I chimed in with my thoughts. My
thoughts are based a great deal on my visit with Mark and listening
with my S.E.X. amp on his marvelous speakers where I came away so
impressed and overawed that I immidiately bought the best Klipsch I
could afford (and honestly, that I had a snowball chance of fitting in
my room). I don't have my Paramounts yet so I will have to wait
to weigh in on how those sound though I bet they sound great. Its
all horses for courses regardless.

For home theatre I wouldn't even begin to give advice. I am
not into it being purely two channel stereo for listening and T.V.
being something I do sporadically. I am surprised that you would
hear the amp clip with the Moth. I am not completely familiar
with that speaker but given what I had assumed about its effeciency,
and my own experience with 2 watts into high effeciency, that does
surprise me. We were listening on the Klipsch at really high
levels and I heard nothing but sweet music. But if you heard it,
it probably was happening. I have been told I listen at pretty
low levels compared to others and
being over at Mark's I believe it. I find it physically painful
to
listen at the levels I have heard numerous other people listen at so
dynamics, not clipping, is usually my main concern at low levels.
As far as Welborne goes, I have never done business there but would
just caution somebody to go read the posts about getting orders filled
and make up their own mind taking your post into account as well.
A lot has been posted recently. The products have a good
reputation for sound, no argument there at all. That is not where
my concern was directed. -
and maybe audiogon. They come up frequently and one will be near
you eventually. I got mine from ebay and they appear to be in
very good shape.
