Default TEK 465M Scope - Power Supply Voltages

Jim,
I disconnected the HV drive at pin 10 of the transformer where it is
connected to the HV multiplier. Fuse still blows. What next?

Jim,
What do you suggest for the next trouble shooting step? Unplug the
CRT? or?
Thanks,
Dale

I left my 465 on for a few days and now there is no trace. All
voltages are correct except 2KV, 95V and 32V Unreg. The 32V blows
the .25 amp fuse. Any suggestions?
Thank you,
Dale


I'm looking at the 465 and the 465B manual, and I don't see any of
these low voltage supplies. The only unregulated outputs are +120V
and the unregulated source for the +55V regulated output (actually
+78V) and +15V unregulated. . There is a +110 regulated output,
but no 95V output. Which version of the 465 do you have?
(465/465A/465B)

It's a 465M,not truly a *465*. It's more like a 455A2B2 with wider
BW.

The 32V-unreg runs the HV,he probably has a bad multiplier or CRT.

disconnect the HV drive to the multiplier.The 95V should come up and the
32Vunreg fuse should not blow.

Do you have a 465M service manual?
