- my favorite amplifier: Something nice
- Completed builds: Alembic-like state-variable and sallen-key filter preamps
Lovepedal Eternity
Phase 100
Brown source
Fuzz Face
Flipster
Alembic F2B (tube preamp)
Opamp and FET buffers
Loads of speakercabinets and ampracks
Busy building a modular synth (ssm2044 vcfs, preamps, ADSR's, VCO's, VCA's)
Tables
Bookshelves
Basses
So many things! :D - Location: Rosmalen, NL

Legibility of the schematic is absent, unfortunately, you can make out the rough structure, but component values can hardly be made out.
Also, can't find the two reverb sections....

The issue here is probably the original source compression level. I found the UK version (same schematic) which seems to look slightly better. To add to the confusion, I found an Italian version, too, and it's not the same
Also, the reverb section is using a Hammond spring reverb tank, see page 36 (5/7 in our PDF).
LATER: Sorry, no OCR. I'm not that well versed as Modman in OCR.

Thanks! That's better indeed, lm386 as a reverb driver.....

I built this preamp in 1987, fully tracing the circuit with a pencil as we couldn't do a PCB this size with our UV machine at the electronics club...
Frankly, you can absolutely do without this preamp, actually, the "clean" channel with the reverb is on par with cheap 80's transistor amps, the so-called "lead channel" with its 5 band EQ and its FET distortion which, as the author says, "according to people who know the tubes sound that tested his preamp, is on par with the sound of tubes amps" he himself calls a "sweet myth", well, let me tell you that this guy probably never touched a guitar in his life : his lead channel is totally irrelevant and those knowing about the tube sound at Elektor in 1982 probably were only implied in HiFi...
Frankly : do not waste your time and money building this, period!
If you want a good transistor preamp/amp, go for the Rockman Sustainor, the SansAmp, the Jazz-Chorus or the MiniBrute.
There's another Elektor guitar preamp that is more simple, it's not formidable too, but they made a very interesting kind of resonant parametric filter as a complement for the tone stack, this part of the preamp can serve as a very interesting inductanceless wahwah... I'd be pleased to find back this article as I've lost my photocopy and long dismantled it to reuse the parts at smth else after I built my first tube amp around 1991...
