design parameters etc/good sound

[tomg]

The trick is not to blow it up! My SA-5200 and SX-727 
are still kicking. Ahhh output transformers....... There is
something wonderful there. I miss my chrome plated 
Stereo 70 and nad pre sometimes but...nahhh! 

Seems like there is a SX-1250 in the shed?  I know
there are a few newer things....anyway..

BTW I've got an old EICO HF-22. This a 22W
Mullard type tube mono-amp. Maybe the best sounding 
EICO of all and the transformers are excellent.. I got it
thinking I might use the guts build another guitar amp 
but that would be a real waste. I had plans to put it on
my DIY-Store page but the page isn't finished and we
are talking audio. So if someone wants it make me an 
offer. You will have to pay shipping and it's not going to 
be cheap!

BTBTW..I have a few thousand service manuals and
parts that cover the last...oh... 30+ years of audio/video 
service. These will eventually go on sale too. So if you
kept that old Marantz or Pioneer thinking one day you
might find a manual...you could be right.
