Halolight flyback?

I recently picked up a Halolight but unfortunately it won’t make any HV and fails ring test after recap. If anyone has a Merit HVO-54, Thordarson FLY-76, Triad D-49 or other suitable replacement please let me know. Chassis is a 1-533-8.

Just to make double sure the old fly is bad I subbed in an air core HV transformer, which immediately made a nice fat arc. So the old fly is definitely bad, must have a primary short since it’s all discolored in that area like it got really hot.

I’ll post a shot of this set running next to my Saratoga, soon as I get a decent picture on it.

Part received, thanks again Eric. Any chance there’s a wiring diagram for the HVO-54? Not really sure how it goes in.

No, I looked through the box it was in and didn't find it.

If someone has a Merit catalog it likely would show their fly types schematically with the terminals numbered.

Never mind, there was a terminal conversion chart in the back of the Sams. Next issue is I’ve only got 6kv, I’ll play with it a little more this weekend.

HVO-54 is installed and working, but it’s only making around 7kv of anode voltage. Anyone know if this particular fly is OK to use with low B+ chassis, or does it need 385v like other sets? Sweep width is good, output tube draws around 160ma, just low HV.

I noticed that Fly had been soldered on before I sent it to you, I wonder if it could have been a dud from the beginning?
