Here's more piccys.
I borrowed a double beam osc to adjust the o/p from the GDT secondaries to make sure they were 180 out of phase...…..if not, the Mosfets would go to smithereens, wherever that is.
(The slight difference in amplitude is the osc amp adjustment slightly different)
Also a mock up of the complete SSTC. The small blue toroid at the bottom is the feedback coil. The Mosfets are on the heatsinks in the front. All the mains power supplies are slung underneath the MDF base.
Also close up of Mosfets on heatsinks. 2 PC fans each end for cooling.
I've tried to keep all the leads as short as possible and the primary coil
will be just above with short connecting leads.
Those yellow caps (.33 mf. 2kv) were 5 quid each...….don't tell the wifey.
Blimey, if this ever works I've got to make another identical one AND get the GU81s running in tandem again...
…...I hope that Bach eventually likes it all.
