1961 zenith 16H32 “the barrett”

Saw this set for sale on fäcëböök and I thought it was cool so I decided to get it. After a 4 hour round trip, i got it home and plugged it in and no picture, sound or HV. I checked the fuse and it was cremated so i put and new one in and this time the 3DG4 rectifier starts throwing purple sparks and blew the fuse. I took the chassis out to check the filters for shorts and no shorts were found so I thought it was the rectifier tube shorting when the HV starts so I ordered a NOS 3DG4. The new tube arrives and i put it in the set but this time the HV starts up and i can hear the vertical running, and then a raster! I put the chassis back in to the cabinet and reattached the tuner and was surprised with strong snow and loud sound. I hook up the converter box and there was a nice picture but the horizontal won’t stop rolling. I asked around as to why it’s doing this and someone told me the phase detector diode was causing this so a fellow collector sent me an exact replacement and as the replacement was on its way, i tested all the tubes in the horizontal circuit and all was good except for the 6HS8. The 6HS8 tested very weak so I ordered one and its still on its way. I have decided not to replace the diode until i see what a new 6HS8 will do. I’ll update the horizontal problem when the tube gets here.

An update

I have now got the new 6HS8 in and i have replaced the phase detector diode and all but two caps. The horizontal is somewhat stable but not good enough. I replaced the 6GH8 with a NOS one- no difference. Soon i will be replacing rest of the caps and a few resistors in the horizontal circuit and a few resistors on the 6EM7 to hopefully get rid of the annoying lines on top of the picture.

These sets were so damn good its almost a crime. I loved working on
them but didnt do many cause they didnt break. Best B&W sets ever
built IMHO.

For the vert there is an electrolytic in the cathode of the V out.
Its usually part of a can. Next is the integrators, 3 legged discs that
have 87 on them and a color dot. After that caps in vert feedback. Also
watch for high value resistors in the V size area.

I just got done replacing the bumble bomb and ceramic cap. Now the set shows some more improvement.

I sold the bumblebee cap on ebay for $25. I got a sams for the set and its helping ALOT. When I order rest of the parts for this set, that should be it. I am sick of working on it.
