Don,

I built the K-502 stereo integrated amplifier kit and use it with a pair of single-driver Fostex speakers. The amp performs way above its price point.

Cool. I think I'll have to try one then. At that price, it's kind of a no brainer, hard to pass it up.

Have you modded yours? Could it use better transformers and caps? I would guess that is where cost cutting was done.


Thanks, Don

Don,

For $125 or so, it really is a no-brainer. Although I'm sure it could use better transformers and caps, the real weak point is probably the potentiometer. I built mine bone stock, precisely so I could hear how it sounded "as is" and without designer parts. I'm using it in a dusty environment -- my garage/shop (lots of speaker-related MDF dust, evil stuff) -- and the open (not potted) pot understandably got dust in it. I try not to change the volume too much. This should not be a real problem in most settings, but the pot is a cheap affair and the amp would probably benefit from a better one.

HI DOn,
I built one stock. Listening impressions have been already recorded on audioroundtable, at the thread starting at:

It sounds pretty good. I plan on changing the caps. I'm going to leave the trannies stock, since imho it would destroy the cost effectiveness of the amp to do that. Actually, it sounds pretty good stock. Read more at:
