Hello picked up a Eico-ST-70amp a H H Scott LT-10 and a Dyna -Pas all free.. Is the Eico amp good, its all there a bit of rust and has not been moded at all nor have the others..Where can i find info on all three.. I got a Fisher 9335 system for 20$ too it works great thanks for the replys Angelo :smoke:

Dynaco PAS Schematic is here :

There are tons of modifications available for these old units - personally I'm in the 'anti-vintage preamp' camp. Once you upgrade the aged pots, selector switches, RCA jacks and circuits you could almost buy a newer (but still used) ARC or CJ. But hey, some people just enjoy working on stuff like that. I've owned a few PAS preamps in my life and even stock units provide an extremely 'tubey'/warm sound that helps with poor digital sources.

The EICO ST70 (off the top of my head) is a 35WPC 7591 output tubed integrated amplifier.
Triode Electronics has the schematic : http://www.triodeel.com/eist70ps.gif

The EICO ST-70 is a very nice amplifier.

I second the comments on the Eico amps.

That's a great price on those. :thmbsp: Seriously, very nice score. Have fun restoring them! They all deserve it.

HHScott.com has info on the LT-10 - a 42 page instruction book. If this is the same as the Scott 314, I have the Sams folder. Sams Photofacts has a folder on the EICO ST70- # 579-6. I don't have it, but they're not hard to find - even many libraries carry them. The EICO site is down, but thanks to the Wayback Machine, you can find something here: http://web.archive.org/web/20060222141120/users.erols.com/fiddler.interport/ST70.HTM

And of course the Dyna - Triode electronics has the manual and schematic at http://www.triodeel.com/schindex.htm

Lastly, I've never HEARD of a Fisher 9335...

Hello thanks for all the info! Igot parts ordered to restore the Eico.. Plan on using a Fisher digital tuner with it and a pair of speakers not sure which ones yet.. Will replace all electrolitic caps and check all resistors! The Fisher 9335 it solid state suround sound with 100 watt amp works great.. Cant wait to hear tube powered amp. They were all free cause my dad had them and he past away 10 years ago and i fond them in his summer home garden shed no less ! Had to battle 2 huge wolf spiders to get them gr see ya Angelo:smoke:

I'll concur on the EICO. The 7591's produce a nice sound.
