21-CT-55 has a new home

[miniman82]

Slowly powered the chassis on the variac (how did I ever troubleshoot without one?!?), and only got 20 volts of B+....

Predictably, both of the caps in the doubler are almost completely open leading to very low voltage. Jumpered one of them with a new cap, and got almost full voltage and a decent looking waveform out of the horizontal oscilator!

Now the recapping begins...

That leaves me with a lingering question though: why on God's green Earth would the PO have replaced almost all the caps in this thing, only to not replace the ones that matter most? I always begin with the power supply when it comes to caps, but it appears the opposite happened here.
