Anything needed to be changed on Shunty if I use a 36v-0-36v transformer? Found a 72VCT 50VA transformer that is much smaller than the 250VA 84VCT I found earlier - but I guess 50VA might be too anemic.
I do not need that much gain planning on 5 or 7 - so a lower max voltage swing does not matter.
Still looking for suggestions for good source of EI transformers - only sinker is that I am going to need 240V primary.

for Shunty:
change one of zenners (in D1 - D5 string) for 4V7 , so - you'll have ~ 40V after Q2
set (with WR1 ) output voltage to 30V
in case that you can go so low - increase R9 to 7K5
same procedure for negative side of Shunty
you'll be fine even with 50VA , just look is it too warm .......... in case that these 50VA aren't real 😉

Looks like someone build and tested a lot of preamps in that case.
Now who would ever do a thing like that, to such a nice case
😕

Magura 🙂 / whom is contemplating the option of making a new rear plate for Steens pre box.

you two are crazy danske & dutchie
Wonder if those ALU flatbars will be replaced with something like this ?

There is a great chance for excactly that to happen😀
How did you figure that out😕
🙂
I had a feeling that you would have something like those heatzinks laying around 😀 the LL setup of the heatzinks in the picture has nothing to do with your avatar....i think😉

Wow - are those an exact fit?
Where did you get them? Fischer?

No they are recycled and cut out to fit from a bigger heatzink

Steen, you're the man! I knew it.
I still wan't to see the frontplate

Work in progress almost finished.
(Not speaking of the casing. I think I will follow Holgers suggestion on german fora : buy a ML 32S. Throw away the inside ... (Holger : ich scherze nur.
Nice INt 150 review BTW.
I like your style.)
Just waiting for some missing caps for shunty.

Zhe-Modski should be spanked for making me thread kiddy M3.
The tie-strap thing is kind of fun once you get the hang of it, and so Blue

Nice board, Jacco🙂 Blue tie-straps 😱
Did you fire any of them boards up, yet?

Unfortunately not. I have been working hard on the Pumpkin though, but it seems I am getting a bit rusty from my new way of life. Check the picture😀 I seem to be running into all sorts of probs. YGM.

Dude, my shadow solders faster than me.
Me just finito the Shunthings, they operate ok(despite having half the junk soldered on the Sponge Bob side)
I had to call in the cavalry to identify the pass devices, me saving Fairchilds for better use.
