CT-100 B1001599 Failed Convergence Transformer

[Penthode]

I am currently searching for a MOSFET with Vds of minimum 1000v. In these days of switchmode power supplies, devices of 1000 volts plus abound.

The convergence waveform amplitude of max 350 p-p was so close I believe the additional B+ boost should be just enough to achieve good vertical convergence.

The circuit replacement will be more reliable and not subject to the fragile transformer leakage and failure.
