      Hi, I have a Yamaha C6 Preamp starting to hum, checked cables, solder cracks and caps, still hums. I think some 37 year old caps need replacement what brand and series would you advise? I like Nichicon but will take your advice, you know Yamahas.
      Thank you

      Hi Looking for some help with a yamaha ca-800 . Bought on CL. Worked fine in normal mode but left channel is super low volume in class a. I opened it and used deoxit to clean switches and pots (volume was scratchy and inside was really dirty). Now the left channel is out for normal and class a (although if I crank the volume you can hear a little yet distorted sound)
      Any ideas would be appreciated!

      I have two MA5002 amps and a DX4000 and SP4002 preamps. Is it possible use both amps with one of these preamps in bridged mode without any further equipment?

      Hello, stoutblock recommended you for refurb of my C4. Do u have set prices on certain services? What do u usually recommend on these units?

      Hi Avionic , My name is Carlo I've had my CA-1000 since 1978 it died eventually in 1990
      was told at the time it couldn't be repaired but I didn't believe them, just recently I came across this site and you , I would like to bring the CA-1000 back to life but only to be used as a pre-amplifier with one my AX-592 amps I feel the AX-592 have an inferior quality pre-amp section , my question to you is this what is the one part in the CA-1000 that would make re-birthing pointless , the transformers maybe? I hope my question makes sense , I am willing to spend around $600 to re-birth it.

        Why did they say it couldn't be repaired ?

      avionic, I am wondering what your availability/interest would be this summer to rework one of my HK 330b's. Both are starting to get soft transistor hiss. Do you work on HKs as well as Yamahas? What would a ballpark range be for the problem transistor + cap replacements? These are my oldest pieces of equipment, but I really do like the sound of them. Thanks for any thoughts...

      Thank you SO MUCH for the reply regarding the loose wire in C-4...amazingly generous of you!

      I thought that might have been it, but how do it get it to stay in the hole? I can do very BASIC soldering...is that necessary?

      Also, do you think this wire being loose would create the problems I described? (strange output on L/R - Treble/bass - on the phono stage?)

      Thanks AGAIN!

      I am having issues with no relay click and no signal on my cr-800. Any suggestions?

      I'm have questions regarding a Yamaha CA2010 amp. First, are the switches for the input selector, etc open enough to be easily sprayed with deoxIT and second do you have to only remove the wooden cover to get to them. Thanks, Bob. A direct email is robertwhouston@yahoo.com

      Hello Dave!
      I'm a big Yamaha fan (not as big as you,though!) I have an offer in for a CA-1000 with somewhat weak output on both channels. Any ballpark figure for getting it in shape? I won't hold you to it because I understand you might find more things that need to be done, but I would like some idea of cost. Thank you and I thoroughly enjoy your posts!

      Hello Avionic, how are you?

      I saw some post from you on transistors replacement and I saw you are an expert.

      I need to replace two transistors in my Sansui AU-317 amplifier. They are 2SD356 and 2SB526. Is it possible to replace them with similar or even better performance?

      Thanks and regards.

      Dave! MOSFET POWER ROCKS!!!!!

      Well, with that said, I got a thread for you to check out. Dad and I have been working on a set of family owned Ohm's, and I thought you might be interested on taking a peek at Dad's creative work. If you want, take a peek at the "Ohm Walsh 2 Recap" thread. Hope you like it!

      Hi Dave,
      Just a heads up for you.I got a Technics TA A650 home theatre amp in and needed the SM.
      Found it here.A place called eBid from a seller called quagwest. ( http://us.ebid.net/users/quagwest )
      Don't let the name turn you off.This was a hard to find manual and he had it for $6.99 delivered.No postage no handling none of that cheap crap.
      So if you are looking for an sm maybe this guy can help.
      Best to you,man.
