Make sure to save the old caps so if the next owner wants to restuff them they can.

I was planning to restuff them using the uncrimp method. I am restuffing all paper caps. A lot are bumblebees though so I dont know how I'll get around those.

If you are lucky some have split at the seams making them restuffable....The non-split ones I've never rebuilt.....My only idea for restuffing an intact bee is to cut the ends off then use a drill press or dremmel to gut one, then drill holes on the ends for the new leads to go through and glue the ends back on...I never tried that idea though so I may be way off base.

So nice to see all those pictures of it apart, looks great! I'm looking forward to more pictures after it's recapped and making a nice picture! So glad that set is in a collector's hands!

Thanks for the kind words Dave. I just finished cleaning off the dust and dirt on the chassis and anything left is just corrosion. Cleaning the HV area was like defusing a bomb. I knew If I screwed up anything on that flyback it was game over. Did a slow power up on the variac to make sure I did not hurt anything. Chassis produces a solid 14.3kv with no electrical work done. Now for a set of tubes and some new electrolytics. We are in good shape!

If the shunt tube drags down your HV, check the value of the resistors around the 6BK4 grid.

Just powered it up on the variac again, but this time I brought it up to 117 volts instead of 100v. Fly now produces 19.5kv regulated AND UNregulated. HV section is really in good shape! Going to start unmounting the lytics and will restuff them when parts get here on Friday.

Should make more than that, horizontal section likely needs to be set up.

Im sure it will produce more as I replace caps and resistors in those circuits. Interesting as sams calls for 13 to 18.5kv with a target voltage of 16kv and the admiral manual calls for 20kv (which I am going for and then some.)

You're off to a very good start, I'd say!

Sams has an obvious error, if it’s tuned up right it’ll make 22kv easy.

I know my CTC-5 maxed out at around 19.5kv. It seems happy there.

This isn’t a CTC-5, and the 5 is an enigma anyway. The flyback in these sets looks closest to a 4 to me, but definitely makes more HV than a 5.

Well after receiving my yearly dose of Pcbs and other assorted carcinogens in a few days, the filter caps are finally restuffed and installed and all is well with the chassis. I'm torn on whether to keep recapping or install the jug and see what I get with a full set of tubes and new filters.
