current feedback electrostatic amp
The problem with Xicon is max volt: 350v max (271 series), 500v max (294 series) vs 700v max (Koa MF1 series 1/2w). Edit: I'm reviewing the technical sheets and I see that the data is similar for both the Xicon (293 series) and the KOA (CF1). All my BOMs are with KOA resistors

Nop, for electrostatic amps I use this KOA. Metal film 1/2W 1% 50 ppm (or 100 ppm)

current feedback electrostatic amp
For resistors I used Koa like in other electrostatic amps. Transistors is OK. Front transistors I used PBHV8560/PBHV9560

and now for something completely different part 3
Trying to measure all the transistors. On ebay you can find a tester for transistors like this or this...

Match components always helps something. Do it if you can.

Another 3000~4000$ top model? I hope the 009 comes down at a decent price...

Yes it´s correct. We used a little vaseline in the workshop to adjust the rubber seals on the engines that we repaired.

Thanks Sorenb.

The transistors on the inside, Don´t need a heatsink? For the temperatures that Mwl says, I think I'll need a big chasis.

overkill? not overkill ... just cautious. ?

Pars, is it like this? You have hard work ahead. ? The power must work below 35v (the preamp works at 24 volts really). I don´t think you have problems increasing the capacitance but the space is quite limited. I would try those Panasonic TSHA.- Why no KG class AB ?
Pass amps (not First Watt) work as well. No?- goldenreference low voltage power supply

Woooow, nice discovery Thanks!!! About drums, I really like the drummers that play syncopated, like Baker or Copeland - Preamp recap
