Joule Electra preamp and Aragon 4004 mkII

@foster_9

I think I can help. Reach out to me via e-mail and I can e-mail you a 150MKII manual I have in PDF (the manuals were often copies of copies, so some pages may not be easy to read, but it will do the Job). My Joule Info web-page ( http://sigsound.com/classic-product-info/joule-electra-info-page/ ) has a bunch of product info/literature, but I don't have any manuals up there yet though I do have a number of them (I think they are a few I still need to scan in).

The jumpers in question are the two located towards the rear of the circuit board. The default higher impedance setting is the jumper used on/across the front two (of three) pins. The lower output impedance setting is with the jumpers on the rear most two pins.

P.S. Yes, Joule-Electra is no longer in business - Jud retired and close up shop several years ago. I do provide service, support, and upgrades for Joule-Electra gear (even though it can be very challenging to work on gear with next to no technical documentation!)

Feel free to reach out to me via Audiogon or e-mail, phone etc. I'm not on these forums alot, but will get any audiogon messages.

Cheers

@atmasphere Boy Ralph, that brings back some (fond) memories! Me and my older brother shared one of those in my early teens. My dad picked it up used - basically it was my first amplifier! No wonder I like tubes so much! I have to imagine a refurbished one with some updates/improvements would be pretty sweet on a pair of HE speakers.
