Dueling Heathkits

[zeno]

Looks like the sets been slapped around a bit ! Agree with
KF4RCA, nice call BTW ! ( de KA1YHI) Looks to be DGS socket
with one pin broken off. Also the thermistor looks pretty toasted.
If it opens the set will run through the big VDR & it will
brew up with much smoke & dripping mung. Probably 120 ohms
cold but check the manual.
If this uses the RCA vert out design IIRC it uses a yoke coupling cap.
Typically a 470 mfd 200 V. It hooks between the two vert outs
& the yoke. Causes anything form small to zero vert sweep.
Also used in cheap to mid line stereos & a common fail.
A SS vert amp & out are no different than an audio amp & out
often.........
