What a screamer! :shock: L channel with the negative grid current is off the scale. Flippin' 'eck. :shock: Your display (and timebase knob) seems to be saying 50 uS per division, 9 cycles on the screen so I make it slightly under 20 kHz*.

Re: Soldering Varnished Transformer Wire

If like what Danbury used to use, will melt and burn off at 400°C, he had a machine to dip the wrapped terminals (with still enamelled wire) into a very hot solder bath, which melted off the enamel then the solder er, soldered it.

Re: Negative grid current WTF?

Any way you can check if it's oscillating at RF?

Negative grid charge is the kind of thing an oscillator valve can do, e.g. radio local oscillator, and which shuts down the gain so is self biasing. Might account for the clipping too. (?)

Re: Next Owston meet 30 june/1 July 2018

Sorry I couldn't be there, was still in Wales, originally wanted to finish the tour at Owston but got all too complicated, too much to do too little time.
