Interesting to see this amp come up with some commentary on Mark and 18Watt.

Re: Mark Durham Vajra JTM45
Some nice playing out of a very nice sounding amp. I noticed the "Vajra" 18-watt build in the documents here. The 500KL pot looks like a trimmer for the other "300K", noting the parallel 750K. What does "P/P to SE" mean? "Push/Pull to ....?" Single ended?

Yes. If you look at the P/P to SE pot, it grounds the signal on the inverting side as the pot is rotated to SE, running the amp in pseudo-single ended mode. This unbalances the phase inverter too.
