    leok,

    In the CJ MV55-CAV50 the only thing you have to do (to wire for triode mode...) is to move - by resoldering - two jumpers and remove two small capacitors. After this simple operation, the amplifier works a treat, without any problems whatsoever...

    Yes in coma and broke when i  have to sell my laScala and than the Belle, to start a family...

     

    i was always hoping for a pair of Heresy, but could not find something affordable and to go with my taste (don't like black speaker), and Sunday, out of nowhere i had the chance to buy a pair of Forte to go with my impulsive purchase of a CJ on ebay.

     

    i have wait 18 years to buy a CJ CAV50, so i guess i am very patient....

    Finally, i have bought some klipsch speaker, but could not tell if it is Forte, Quartet, Quorus or else

     

    On sticker it is written:

     

    Type: FOR II WO

    serial 90018494

     

    90-19426 02/20/90

                      03/09/90

     

    So could someone explain to me the Klipsch Sticker and tell me what i have purchased, i know it is Klipsch Speaker, but more precisely what model?

    The beast has arrived, lovely sound, i am very happy!

     

    One question? as EL34 replacement, what do you suggest to put in there? What i have on it is mostly JJ as 12au7 and chinese 12ax7 and 6ns7 and el34 are sovtek, since i have purchased a use one, my guess is tube could have some mileage on them? so what would be an affordable replacement? in a tubesture kind of way or tubedepot way?

     

    Thanks for anyhelp provided!

    Inexpensive hifi DAC found - henry audio

    "Cheap" is such a negative word, at least by connotation.  I would welcome an inexpensive quality DAC.  I want nothing to do with "cheap."

    Order the odioquest, will listen?

     

    Change the cheap for inexpensive, but it is bizarre as our society grow older it became sensible for wording? so now we are not old anymore, we are experienced and we are not a society, we are a community,... ;) and it is not wording it is marketing or branding...

    Just to let you know, lately i have a hum, after few research myself and with the help of the cable guy, he discover that the cable company installation has forgot to ground there cable before going in the house, so when i was hooking tv on computer, there was a hum in the system, took me two week to find the source and then cable guy work 2 hours, checking cable from the house to the pole.

     

    Still enjoy my amp, great bargain, lovely sound.

     

    One upgrade i want to do, is to replace the potentiometer for volume, any clue to what i should put in?

     

    regards

     

    ps, i am looking maybe for my other hifi room to buy a cav45 from CJ, is it a good choice? any comment? maybe i should star a new post for this one?

    noise floor in db

    in 2-Channel Home Audio

    Good evening,

     

    as always, i am tuning my listening room and here my questioning on the subject?

     

    How high, is the noise floor in your listening room, when everything is quiet?

     

    i have a reading of 35db? is it good?

    Bryston B60R vs 11B+4B duo

    in 2-Channel Home Audio

    Posted

    Good Day, 

     

    I have 2 system, one tube and one transistor and i am thinking about to make some change in my transistor system

     

    i have the Bryston duo 11B+4B amp (big and heavy with the ST upgraded in it made by Bryston in the old 4B version), since i don't have a turntable anymore and find this duo little bit powerful, i think about downgrading my transistor system to the new Bryston B60R with dac inside. Anyone try the new B60R? how is the sound, smoother? would you recommend it? or should i go with the 2B LP pro and keep my preamp, in case i go back turntable? what do you think?

     

    regards

    Mike Stehr is most likely correct. Most 300B/2A3 SE amplifiers have a noise adjustment pot. Bias adjustment pots are mainly for push pull amps. As long as you stick with the same kind of tubes you should be good for different brands of the same tube. OPT is an abbreviation for output transformers. Nice looking amplifier and I bet it sounds great. I have heard the difference between a 2A3 and 300B is "not much."

     

    I just looked on Ebay for a price, great deal. I do not exactly know what the seller is saying about being used as Class A or A/B. To my knowledge all single ended tube amplifiers are class A. Probably just a sales pitch for those that do not know the difference. As much as I like buying American there are great deals coming from China on tube amplifiers vs American prices. You can expect the prices to go up soon due to tariffs. 

    So my NOS Marconi are in good hand, the amps is long to break-in almost 6 month/12 hours a day, but after that smooth sound, and voicing is incredible. NOS ad a little something on the warm side and this amp is dead quiet (i mean noise floor), one of the quietest i had so far.

     

    As far as i could afford it, i'll go with north american product, but here, it was a steal deal and most likely "tweakable" if needed by my 80years old technician that help me in the past bring back to life old tube amp and tube receiver.

    Those are most likely the bias adjustment pots for the amp.  There may be a bias ranged printed near the two  adjustment pots.

     

    Until you find out the bias adjustment range I would keep the tubes that came with the amp.  A lot of people want to quickly get rid of the Chinese tube.  They just assume that they are not good.  Actually, they make some pretty good tubes.  China and Russia never stopped using tubes when the US went thru the transistor age.  A lot of tubes made in China and Russia are re-branded for overseas sale.

     

    Try and find a manual for the amp.  Let us know how you like it.

    no ranged print.

     

    NOS Marconi are on, couldn't wait, but will keep china as backup

     

    and no manual, but found seller contact and send my question, so far the only thing i learn it is for the noise floor. it is suggested to play with them until there's no noise? not sure if i understand this and why?

    Could not resist that candy red look! it work flawless.  And banzai, i have put the tube on, sound amazing! but not sure i have the proper "noise" adjustment?

     

    only downsize, no phone socket.

     

    ps

    i found back the seller, send a question, will wait and see!

     

    Sometimes i am to much in the problem to think outside the box... Thanks

    Good Day all,

     

    i have purchased a 2a3 Bowei integrated amp on ebay, and it plays well. Now i want to upgrade  chinese tube on it. there is 2 potentiometer (behind the tube), i could access with a screwdriver. Does anyone knows what is the purpose of those potentiometer?

     

    Could not find anything on it, so my guess was to ask you all?

     

    Also tube on this amp are weird, could i replace them with something more standard or NOS? exemple 2a3C=?; GZ3=? and 6h8c=?

     

    regards
