Gainclone vs Vintage
How do gainclones compare with quality vintage receiver/amps such as HK 690i (or any other ones you've heard)? I've noticed that some of the older amps or receivers are selling for silly prices.

Need advice on rehabbing an old stereo console
First, sorry if this isn't the place for this thread! Now, I know, I know, stereo consoles are the worst. The speakers tend to be bad and the design of putting the turntable in the same body as the speakers is awful. I'm totally with you and I agree. But I think they're awesome anyway. This... -

Project 5500. Big fun or ....?
A couple of years ago, a friend of mine came up with an old Pioneer amp. It was a SA-5500II. "It only hums" he said, "maybe you've got some purpose for it?" Ofcourse. But then, after I opened it up, I saw the two tiny STK like modules. Pioneers own little crap circuits. I closed it and dumped...- Rob DeFries
