Please list the well known technicians here whom the dealers engage for repair for high end audio. Sometimes, it's better to go direct to these technicians to know the truth on the state of repair. I believe these technicians may be part timers or freelancers for the dealers.

I am looking too for quite a long time- but no rush.as i have a few vintage solid state hi-fi needed to look at.
but parts are hard to come by. i dont mind replacement of IC and transistor ( mine is SAE pre and power). cost is no issue, as these gears are pass down from my late father- so it held sentiment values.

You can always look for Adrian from Memory Lane. But he's usually swamped with too many stuff to repair. Sometimes even the shops at Adelphi too send him stuff to fix

Usually for old amps, the electrolytic caps will dry out and the capacitance will drop. Some will even overheat and pop. The old carbon composite resistors will drift in value and some will even crack due to prolong heat exposure. Then there are the switches. Some are impossible to find replacements when they do go bad and nigh impossible to refurbish. I haven't mentioned the internal wires, ICs and transistors, and power supply transformer yet. Restoration with original parts? IMHO, a bad idea.

Would I repair classics? No. It's not that I haven't tried. It's better to strip out the entire internals and rebuild from scratch. Why? If a faulty component is replaced, it will cause a cascade of other component failures especially if it's very old, say 30 odd years. Cheaper amps don't last as long. Furthermore, without a circuit diagram, you'll be wallowing in the dark.

A case in point. I have my Dad's old Sansui Au-222 that's been crackling for years. I have replaced all the e-caps. I have replaced most of the internal wires. A couple of the throw switches have broken off and the only way to replace them is to salvage another Sansui. Almost all the transistors need replacing. Luckily there are modern equivalents. The binding posts and RCA sockets have tarnished. The casing has rusted. However, I found the circuit for it and I will repair it because I grew up with it.

So if you want to refurbish an old amp, do learn to do it yourself. I did and I'm not a tech.

My 2 Lira's worth.  ;D

I used to do this kind of work on vintage gear but the labour cost is many hours (cost is high) and hard to find parts as Sanjay noted. It’s a labour of love and no guarantee something won’t go wrong and possibly render all the effort worthless.


I no longer do this work so please don’t ask me. Good luck if you can find someone capable and affordable.

I have a pile of stuff that pushes out squiggly waveforms from smaller squiggly waveforms that sometimes come from 1's and 0's.
It's wonderful to behold as long as you don't let the magic smoke out.

Life is short! Enjoy the music while it plays, when it stops, there might be a chair for you...or  maybe not.
