Have you tried B&K, used ST140s go for $2-300 used. The later models are 105 watts per channel. They also run relatively cool. I purchased mine new 8 years ago and have only had to replace it fuses once due to my monkeying around without thinking. They are not very detailed amps, but are extremely smooth.
I need tube sound without the tubes
I've been running tubes for awhile and am just about fed up with all the problems that tubes entail. I've spent the past five years putting out fires...sometimes literally. Problem is I love the tube sound. Now, I'm a poor social worker with a taste for caviar and a pocket for tunafish...anyone out there have any recommendations for a great cheap amplifier that sounds sorta tubey. I need at least 75W per channel to run my speakers effectively. Cheap, my doctor and lawyer friends, means around $400. Maybe I'll be able to afford more in my next lifetime. Anybody want to make a donation to charity?
