Got those two 20uf caps installed. All working well. Tested each pin #2 and had nice low voltages (IE: .02 .01 etc) except one which was at 1.2v This was adjacent to the worst looking coupling cap in the amp. Its really sweatin there so I'm suspecting its kaput. Getting my list together for ordering and one of the smallest caps has no value on it, just a number 475. Anyway, I thought I would just measure capacitance and go with that value?
I moved the slightly brighter tube to another socket and the brightness moved with the tube so that one may be a short timer.
When I get all the new caps installed I will post a picture. Thanks again.

Atlas makes an SD-70 siren driver which I suspect is really PH5VH in disguise.

I was working for the railroad in New Orleans right after Katrina. Locomotives sometimes kick railcars down the track. Two cars collided right behind me. Sounded like Dynamite going off. My ears immediately starting ringing. Hever had that happen before. That along with a knock in the head and my hearing hasn't been the same.
Now if Im really careful about my sound systems volume levels and wear earplugs anytime loud noises might happen, I can really reduce the noise residing in my head.

Welcome to the Tinnitus club. Very common affliction I'm affraid. I have had it about 4yrs now. It seems alot of things affect it however. Wearing earplugs as mentioned is very good advice. I protect my ears from any loud noises. I cannot hear above 16K myself. Im really enjoying my 2way speaker setups.
-
Yes, thats exactly the setup. Off #3 pin parallel with a resistor. There are two in the amp and I'll get those swapped after work today.
I'll give it a good listen with the bypass caps replaced and test for DC on pin #2 of each.
Thanks for the help guys!

A 25uf barrel cap to the base of the HOT 6BQ5 indicates open. The opposing one (other channel) charged and discharged properly. So maybe that explains the hot tube, but it was making music out of both channels with this bad cap?
I have found two Spraque Atom 20uf 50v in my stash of electronics. Wonder if that would work ok?
-
I always make sure power disconnected and that caps are bled down before surgery, anything else I should do?
Of course I have already pulled this one, removed all support wiring, found and connected primary, variaced it, connected a source and listened to music.
On electrocution, I have performed high voltage electrical service work for the last 20yrs and was hit by 480v once which was not pleasant but not terminal either. I know of many deaths due to industrial electrical accidents but have never heard of a tube amp death, have you?

Orange drops and PS caps. Where do you source those? I was thinking parts express on the RCA connectors. I check them on the caps too.
OK, found some. Check out the Orange Drop kit at the bottom of this page.

Hey Mike, thats a good looking little amp.
Guess I could swap out the brighter tube and see what happens. Im gonna install a proper switch, RCA inputs, clean it up. What brand caps are you guys putting in these units?
I'm developed a bad habit of looking for consoles in the garbage and at the thriftstore.
-
Oh my. CB, just had a visual of you stradling a pine tree! NOT a pretty thought.[

Found this unit on the way home from work. I was in an old non-working console at the local thriftstore. It is out of an 60ish Sears console. Service tag revision '64. The amp itself works quite well. I never can seem to get the old FM tuners to do squat. I noticed one of the 4 output tubes glowing a little brighter than the others?
I've seen several SETs with the 6BQ5 compliment. Just wondering if the push/pull was as common.
-
Dean, thanks for the review. You mentioned this: "the Virtue 2 gets incisive as you push the volume". Could you elaborate on this further?
Im very interested in this amp and how it might perform with horns.

Good luck with the recovery. No Sugar Daddys in your future.[

I have a membership at Sams club. Is it me or do they get manufacturers to make versions of products just for them?
Kinda makes it hard to compare prices.
Sams sells the Model: BDP-BX1 model Blu Ray Player. Who else has that one?Sonys TVs there have different model #s and features than those found at other retailers like BestBuy, etc.

Hmmmm. I really think you should avoid Colters place. He will get you over there and introduce you to some speakers for sure. Heresys galore, etc, etc. But before you leave he will probably have you listen to some Jubs or MCM setups or who knows what. To be honest, thats just not anyway to treat a guest considering Heresys.[<

It's confusing, only because the industry standard is to define a driver by it's throat size.
What you just said.[^o)]

For instant improvement for any color coax in digital setups simply wrap a stripe of orange tape at both ends. All problems solved.

Greg, compared to the 2" drivers in your upgrades, these are indeed 1" drivers which is a stretch at that.
Note: My JBL 2" driver has 4" voice coil
K55 1" driver has 2" voice coil
Look at the spec. on your BMS driver, it may have a 4" coil too.

Seems like I remember reading about those fine units. Doublecorns?
-
It appears to come down to the same ole thing, wire size. I suspect the more expensive ones use bigger wire? The pins on that first one look really big though.
-
In the circuit on the Ebay are there resistors in series? Im wondering how can the signal be better if there are?
-
Way to go Danny, slipped out the back door while nobody was looking.[Y]

I used to get those all the time too. Can you say CON ARTISTS. I figured out something with those guys. When they call, tell them how happy you are that they called. Ask them alot of questions about where they are, the weather, family, hobbies, etc. Keep them on the phone for as long as possible. The calling will drop off sharply I suspect.[6]

My 5yr old and his 4 cousins ages 5,5,4,3 that visit here do not get to watch PG13 movies, period. We looked at Dark Knight (PG13) one night at my parents for a short while and it was way too much. Now get this, next day my son's talking like the Joker. That wasn't cool one bit. His little K5 teacher wasn't too impressed either.[:$]
Also, some PG movies are pretty bad. Really have to watch the movies that your kids watch!

Found a 6BQ5 push pull. Are these common?

Here is a picture with the two orange Sprague barrel caps already installed. The diodes are barrel type center left in picture. Is the sound of the amp different with SS rectification vs tube. My little SET amp is tube rectified.
