ZM,
I saw what the kokanee was selling and I was wondering if you also offer the PS boards he was showing.
Do you have a thread for those?

those are not mine, I believe
so, you decided to mount them top/bottom
ok with me
No, I bought 4 pin CDs from DIGIKEY not realizing they could not have two pins removed and work in a standard snap in "socket". Luckily they took them back.
I am using the KEMET slit foils as my output coupling caps on the amps used below 500 hz. They are working quite well. Got those from MOUSER.
I added 180 uf of ASC big can PPs in parallel to the KEMET slit foils. Below 500 hz I do not hear any difference than the KEMETs by themselves but I have left the cans "just in case"! Better than having htem sit in a closet.
The above 500 Hz amplifiers use 1500 uF of Ducati PP with bypass caps. These caps are the size of a large motorcycle battery.
Yes, ZM, there will be caps mounted on each side of the board. This will work out just fine. I will have the caps oriented horizontally - this will work out well.

Look for posts / threads by rhthatcher. I think I posted the Gerber files for those when he asked for them. Botte designed the original, and Randy tweaked it nicely. I think he did a GB.
Well, I was getting ready to order the IXFN140N20P for my build and they are out of stock until July at Mouser, DOH!
We have developed an active 3-way system. As a DAC I use a DAC8PRO, which has only XLR output, with an output level of 4.1 V RMS and a 200 ohm maximum differential output impedance. Would a 600: 600 transformer be OK to connect a Singing Bush to this DAC? (I have 2 pieces JT-123-FLCPH)
Thanks a lot!
Thanks a lot!
It would be a problem with a preamplifier because the DAC8PRO has 8 channels. The advantage is that the overall volume and the volume on each channel are adjusted from the DAC.
hello zm,
I want to build this singing bush with 2sk180 parts, but unfortunately i only have a big 20A toroid transformer with 24v single tap
question is, if i had to use a voltage doubler circuit to boost 24vac into 65vdc, what is the negative side that will affect if implemented into this amp.
in theory with voltage doubler
24vac x 2.8 - 2v = arround 65v
and current would become half from 20A into 10A
and it's look like still enough to powering this amp (without knowing the bad side)
thanks.

too much ripple for my liking
voltage doublers are OK for lower currents, but when dealing with 2A++ ........... you already have bucket of other problems to take care of
why adding another enormous problem, on top
