Mouser is about to ship the parts, as always shipping is almost half the cost, THIS TIME I will rig it only with one horizontal output configuration, the 6BG6 is a 20w tube, more than enough for the 52 degrees of the 16LP4, perhaps the dual mode was too much for the Merit HVO-5, and it had a fit and melted down or something, not sure what the total power in dual mode would be, 30-35w?
The OEM flyback did seem to built a bit more robust, so who knows, when it was working with the HVO-5 it seemed to work really well, till it caught fire!!

However, the the X032 seems very flexable, says will work with one 6BG6, and 13kv out with one 1B3GT.
