the case is very perforated below and above the heatsink so there is a lot of air flow and the temp is reasonable.
there are two outputs, one is fullrange and the other is >60Hz. that's what the cap on the back is for
Yeah, it is the pre amp version WXC-50, pretty good SQ, but you need a device to control it, I'm using a Samsung tablet. The setup was a bit of a pain, but once done is ok.
I converted my “Tallboy” Mini J to F5. New tranny. New caps (my frugality buying 25V caps cost me more in the end), and “upcycled” boards from Jim “6L6”. Wired, biased, warmed up, tweaked bias, tested with speakers. This evening I will put my 2 F5’s in my active system and finally hear them for real. The cheap sacrificial Yamaha test speakers don’t compare to JBL hartsfields with a DEQX active setup.

I heard the rawson F5 on which I fixed the safety bits then lent to my buddy as I fixed up his rawson J monos. He fell in love. The F5 is now his.
I finished my 2nd F5. See previous post. After hours of warm up I’m into serious listening. Holy hell. I’m hearing things on favorite records I’ve never heard before. Coming from years of Aleph Mini J and recent J Mono / Mini J combo - F5 brings transparency and mighty grip on the bass. Amazing.

heres my Iron Pumpkin SE 🙂
It is not overly nicely made, old 1000 times used RCA plugs, weirdo cabeling etc, but i like the steel case. This preamp deserved something personal.
The thing i learned (mechanically) ,is, degrease metal with aceton before painting, not washing gaz, that´s not enough.
The signal cabeling is almost ideologically thin : ), hair like predrilled signal cable (to feed LEDs in mikro toy railways.
Soundwise i´m superhappy. Depth, Stage, dynamics all there. But it is to early to tell more. I need a while and checking back to old equipment makes it more clear.
And it is my first build with the function written beside the knob, my girlfriend is happy too : )
happybest and ZM of course, manythanks for the great kit!

Very timeless and simple elegance in all your equipment, noelectrix! Nice family resemblance. Maximum utility and style with minimum materials.
I like how you integrated the selector and 3.5mm input socket.
Dieter Rams would be pleased!

Thanks Zen.
Temp is "low", around 40~50º on IRFP9240 body and 35~40º on C2M1000170D but in general, the heatsink barely exceed the room temperature by a few degrees.
