Well, for one, you can modify SS amps.  For two, as far as I know, a valvetronix amp has tubes as well, no?  I'd need to see a schematic to give you some good modding suggestions.

I just recieved the parts I needed.  All the kits are complete now and ready to go.  Unfortunetly, my post office closes at noon on saturdays, so they will be shipped first thing monday morning.

**edit**
This is for:

Bob N - paid (taking transformer as well)
trevize - paid
steve_m - paid
syndromet - paid

Dreamseller, I'm waiting payment, as soon as it comes in I will ship.

Yeah, its listed as paid in a previous post I had.

Payment recieved.

If anyone is interested, I will let the transformer go with a kit for $25 including shipping/handling.

I used a ruler to cut against, and then cut about 30 times with a utility knife.  15 times "up" 15 times "down" on BOTH sides of the board, then broke the boards.  The best way to break them is to flex them back a forth several times, that way it slowly/evenly breaks.  You do have to make sure that the lines match within 1mm or less of each other on both sides, or you'll get a pretty shitty break.  All in all it takes me about 2 minutes to break one apart.

Sold, no more kits left.

That's fine, the parts to finish the kits should be in by friday so that works out great.

If anyone needs a transformer for this I have one for sale:

It'd be better for single LM1875 use, but you could probably use it for stereo anyway.

I wouldn't go with a toroid for a preamp simply because they are more expensive and also don't normally have ratings under 90VA or so, and you don't need anything that big for a preamp.

Aharon - The boards are in the mail.

Ok, so we have:

Bob N - paid (taking transformer as well)
trevize - paid
steve_m - paid
syndromet - paid
DreamSeller

That want kits.  That leaves 1 more stereo LM1875 kit up for grabs.

Aharon - I recieved your money, the boards will be in the mail monday morning.

Try some putting in a socket and try some various resistors between 200 ohm and 20k.
