Sony KV1722 SCC41 A-B Part search

[klofback]

Yes, this is the old "chopper" power supply model from 1974 I have kept
working for years!

Now I need a high voltage block assy. Has the quadrupler as a part of it.
Anyone have any NOS Sony parts around? Or any recommendations?

There were several distributors I used to get Sony parts from, might be
some old companies still around with old parts, but I dont remember who
they were.

Its Part number 1-453-04-631

If I cant find one, im going to retrofit a NTE/ECG quadrupler into the
circuit. Looks like it can be done. The service manual shows the insides.

Thanks in advance community....
