Burleigh PZ-70

[(*steve*)]

Does anyone have any information on these?

I have a sick one.

I do too.
Maybe we could help each other get them going.

Aha! Mine is actually in perfect working order!

My fault was that I didn't wait long enough for the tube to warm up.

What symptoms does yours have?

Can you see the tube's filament glowing?

Do you have the clear back cover in place?

Do you have the various links in place on the rear connectors? (I think there should be 5 of them)

I must have a different model because mine does not have any tubes.
I have a solid state version Burleigh PZ-70 High Voltage DC Op Amp.
Mine has 2 of 4 high wattage resistors that burned and I can't make out
their values and I can't seem to find any schematics.

Hi @Mudflap, I just realised that I confused two pieces of equipment in this thread.

The device with the tube is an APH-1000 high voltage power supply.

My Burleigh PZ-70 seems to work fine.

If you're still around, I have attached a photo of mine. Tell me which resistors you're talking about and I'll compare it to mine.



The two brown resistors near the top right are 50k 20W.
