ZM & friends, would it be possible to drive the autoformer directly from something like a DCG3, bypassing the jfet buffer?

I was watching Nelson Pass BAF talks, and he seems to imply this might be the case, as long as the pre has the current capability to drive the autoformer circuit.

I'm interested in trying it out at some point, since i'll most likely use the DCG3 as a preamp(and to drive HPs). I think i'd have to switch the jfet buffer out of the circuit, probably at the transformer, right?

yes, omit input buffer , if you have enough Cojones in preceding stage

just take care of practically zero DC going in xformer ....... meaning - preceding stage must have minimal DC offset , stable in time

it is extremely convenient , in fact , on Babelfish M25/SissySIT pcb - there is a 2pin jumper header , intended for exact purpose of measuring/setting input JFet buffer offset , having them (buffer and xformer) connected after setting said offset

so , remove jumper , connect your signal route on second jumper pin , ditto to xformer

Right! I saw the jumper in the schematic, and even read about it, didn't connect the dots...

I believe that I'll start next weekend building one complete SissySIT , followed with proper photo-strip and some explanations ....... so pretty much everything will be covered

Interesting that AI came up. I have a 2D. To demonstrate how much of a bottom feeder and audiofool I am, it is a piece of equipment I would strive to best. A “reference” as the wordy golden ear experts would put it. In combination with an old used Counterpoint SA12 and KEF 104/2 speakers it has been one of the best all around sounds for me. Yes, it did not do things my DCB1 with gainclone or ACAs can do with full range front horns...but it was nice.

it is nice , when made by Greedy Boy , while learning all things , including toobz

however , it is not nice when actually bought for not peanuts money

but ...... situation is that there are much more mediocre tube preamps around , than good ones
