Doing this a long time - built plenty of amps, speakers -- nothing I run is commercially made -- oops -- not true, I often use a Shindo preamp --
but I'm getting old , my basement is full of stuff I'll never use and it's time to sell some of it -- cheap. all of it is amazing, as you DIY'ers know, that's where the value is.
Keep on the lookout for neat stuff coming up for sale --- once I get the chance to post in the trading post.......
