I cheated & got the jig cables for it ! Had them for most old
portables. One repair paid for them in time & grief.......
Usually most low level tubes are a little weak. Have a sleeve of 5GH8's
ready also. Too many tubes & not enuf space.
Next the hoz / vert, contrast assy, tin wiskers.
Most had toasted sockets in the IF strip. While there the 4.5 & 41.25 traps
need touching up.
Changed value on resistors in hoz osc.
After all that you have the low focus jug ( I called it no focus).
A light rejuve gave them snap again.
Funny thing is these & there 19" brothers could throw a fantastic pix
if you wanted to put in the time & tube $$ into it.
Unlike 40 yrs ago I would LOVE to do one again, if only I still had
the resources still
