A nice project might be moving those goodies into a custom made
chassis. I'd be more than happy to help with Front Panel Express work
since I already have the ST-70 transformer templates ready. :)I've been dorking with solid state lately.... It's much cheaper than
tube projects. Further, the results can be thoroughly suprising. My
last project involved gutting and upgrading a Gemini PA-7000 preamp.
I bought the preamp new for $99. It has nice metal work too - a real
steel case. It has a phono stage, XLR outputs and a simple attenuator
with op-amp output buffer... I upgraded all the op-amps from JRC4558's to AD826 (output buffer), OP270 (phono) and SSM2142 (XLR outputs). The sound is FANTASTIC. Better than my tube preamp I'm ashamed to say. Further, the SSM2142's did an awesome job at driving various line-in transformers. It's a cheap project, with very surprising results.Another cheap project would be the legendary JLH 10 W Class A amp
(bipolar transistors, not MOSFETs). People seem to really honestly
love that amp... The devices are cheap (under $1.00). The budget
driving items are the heatsinks and the power transformer... I'm
figuring $40 for the transformer... The big heatsinks (0.6 deg C/W)
would require some scrounging around. A dead or broken Adcom or
B&K might make an excellent transplant candidate! :)-- Jim
