Which amps are the hardest to get parts for?

[6mantoys]

I am always looking for amps and I turn down buying some for the fear of no parts avail.i Thought almost everyone has a experience of the great deal that cant be fixed.

i would dare say that once things started getting digital displays, the proprietary parts started popping up.

What about the yamaha m80? Heard they become doorstops after a while...

:scratch2: Fixable...
Yamaha VFET's may be damn hard to find and costly to replace.

I would say the dual core caps in some top Marantz receivers are unobtanium. The Power Packs in KR-9600's if bad will make them door stops. Various IC chips will also stop units cold. VFETS in some Yamaha and Sony amps are no longer available.

 

[ke4mcl]

this a good reason to love tube gear. all off the shelf parts.

Besides the ICs for the KR-9600, the ICs for the KA-9100 and KA-8300 are also unobtainium.

Heard where?

I call FUD.

They'll keep running if the corrosive glue issue is attended to. Yamaha is not the only brand to experience this issue.

Usually it's an amplifier you like the most. Like a Murphy law...

One more, the ring emitter outputs in certain Kenwoods are impossible to find.

Can anyone fix a Yamaha MX-1000 with what the tech said was a "blown channel"?

How about the G- series Sansui

How about the G- series Sansui

Pretty much all the electrical parts are easily obtained or substituted. Knobs and cosmetics are not.

i know personally the gas amp has a few no longer parts
like stated above it was the amp i loved

 

[phaedrus]

Yeah, a lot of the GAS and SUMO amps use unobtainable proprietary parts.

The amps with the hardest parts to get are happened to be the ones you can't live without them. Anything else you can fix, they have no value. The ones you can't fix are unobtainum so they worth any pennies.

The parts you can't find will be the parts you need.

Anything can be fixed...it just takes time and money. :yes:

 

[KentTeffeteller]

Here's some indicators of hard to find parts:

IC modules (Many STK units don't have good quality replacements available)
VFET transistors (Sony and Yamaha used them)
Early period Germanium transistors
Sanken transistors are hard to source (many Sansui units used them)
Delco transistors used in older Phase Linear amplifiers.

There's more out there but some idea of units with specialized parts issues.

Is there a central post (sticky) in AK where this information is available?
