Step-by-step the classic light bulbs are going to disappear here in Europe. The production is partially not allowed anymore, but you can still find them in the shops (at least here in Germany), because trade is not restricted and there are still enough of them in stock.
Of course they needed more energy, but I think they have had their own charm.

Do you have the Russian KP926A or B? I have a lead on how to get them from a US distributor. So far 8-10Wks but no price yet. I will offer some G.B. action when I find out more. I'ld gladly donate some to you if your interested...

Is the big resistor on the heatsink part of the CRC filter.
I really like the simple nature of this amp with one device. Much more to follow hopefully.

Nelson,
were you serious about having discrete parts made? That is some of the best news yet.

Yeah I get it now. In the past I've used my toaster for testing high-power sound reinforcement amps.

I meant as load for sole active mosfet in amp , not dummy load on output of amp .

look in Zen article ...... or even better - Zen Lite

regarding metal Dale resistors on htsnk , I presume they're 1R source resistors ...

not that's of any importance ..... looking at school board - it really can't be simpler

In Italy starting Sept. 1st shops cannot sell traditional 100 W bulbs any more. From Jan. 2nd 75 W, etc. etc.
It was supposed to be an European law.
We will find them at flea markets aside tubes in the future.
