Up to page 213 now, should finish before bed time. What more could a guy want on his 70th birthday ?
I've found a couple of small things of note which I've copied to my build sheets, so it wasn't an entirely wasted task.

Wise words nick..I see that on all forums,
Erm..... visited a couple and there was a really small sound in the background as I arrived, as if someone had left the world’s smallest transistor radio on in kitchen. Me “are we going to have a listen to you’re amp?” (thinks, wsh they’d turn this tinny little badly tuned in tranny radio off; looking forward to hearing the amp of this legend.) two offended faces “it’s on now”...
Cost me a couple of mosfets and a couple of hours.. I should have read up I bit more, but as ever you dont always relate others problemspre65 wrote: ↑Thu Jun 25, 2020 9:28 am It seems the main reason for blowing the mosfet was caused by unplugging the DC and a "surge" from the inductor.
The recommended action was to hard wire the DC and turn off at the AC supply.
That's probably what I would have done anyway.
But, I'll still fit the zener.
Well Paul, having read the thread in its entirety I was not aware of any "willy waving" at all.Paul Barker wrote: ↑Thu Jun 25, 2020 9:40 am I had a quick look at the circuit, well the one my browser found, I’m not in the least bit interested in even beginning to read a threda which exists so extensive because of Willy waving one upmanship by the proud ignorant people lost in the woods.
If your my way one day pop in Paul. I think you will be surprised.. I think mine will give steves 13e1otl a shock.. there again I may be wrong. But it's in that ball park.
I would, mosfet's gate insulation have a well defined max voltage. No real down size of the 20p zener. Just look up Vgs Max on the mosfet data sheet and use a 500mw zener 5v less.pre65 wrote: ↑Thu Jun 25, 2020 9:28 am It seems the main reason for blowing the mosfet was caused by unplugging the DC and a "surge" from the inductor.

In many ways its the same circuit.I think mine will give steves 13e1otl a shock
