SVT II oscillation/distortion

[drewl]

Good News Everyone!

Output trans is okay. Connector on impedance switch was just barely touching the chassis from previous"fix" from someone.
Plenty of good clean output, no oscillations or distortions.

Now, about the unused secondary taps-
Hmm.
The only markings I can see on OT are DR-28 underneath.
In the 1970 schematic the windings are paralleled.

Here is the schematic to the SVT II:




And the second one is the older version with the six output trans wires like this unit has.

Have a look at page 2 of this one.

What am I looking for that it's too fuzzy to see?

[g1]

Sorry, I thought you meant an OT with 6 wires, but you meant 6 wires on the secondary, 9 in total.
Maybe the OT was replaced with an older type?

[drewl]

Either that or a leftover trans?

It doesnt look like it was replaced.
Did the originals have the secondary wires attached to a plug?
I can't remember.

[g1]

I don't think so. This one shows the connectors elsewhere, but not at the OT. And there's a part # for the OT.

g1 gets an overall "like" for his clear effort in this matter

You know what they say, one man's 'effort' is another man's OCD.

Any and all help is always appreciated.

I usually try to answer a few questions whenever I ask one.
