Need advice on what to build...

[Boscoe]

Basically I want a nice powerful amp. I'm currently using a real old sony receiver which is not nice. It provides lacking non existant bass but sounds very forced and un-natural when the eq is tweaked. Mid range is again lacking although there and sounds muddled, highs are nice althoug hperhaps a little overpowered.

So now I want a great sounding amp like my old akai but with a bit more power!

These are my must haves and I would love to see the diy community point me in the right direction!

-200Wrms into 8ohm at low distortion.
-No TO-3 packages due to the design.
-Pre made PCBs available with a good supply of info on it.
-Parts available to the UK.

The GM clone in the group buy has some PCBs avalible but only in TO-3 but I think due to my requirements I might have to compromise. What does this amp sound like? Good?

Thanks.

Lack of bass sounds like dried up capacitors and mabe the speakers either beein incapable of producing the wanted amount of bass, needing more power than ur amp can supply or simply just beeing placed so that your listening position is right in a node where direct and reflected sound is cancelled out, leaving mostly higher freqs behind.

Sounding forced could indicate either excessive cone movement, a clipping amplifier or a faulty amplifier such as dried up caps.

the 2SA1295 2SC3264 are the transistors you need if you want high power and no TO3 package.
maybe you can make an amplifier with TO3 transistors and replace them with MT200 transistors?

I think it may be the caps then, my speakers sounded great on a previous amp but that one is too underpowered.

Do you have an amplifier you are recommending?

Thanks
