intermittent 60Hz problem -- ideas? suggestions? Help

[CaseyJones]

I've got a couple Tektronics 'scopes that had multiple rectifiers before I scrapped 'em out, they had like four rectifiers in a row. Tek lined up the sockets and skewered them together with buss bars. I suppose it would suck to burn up a socket and then have to get them apart.

I also have the output stage of some sort of oddball transmitter, it used 5 x 6550s with the filaments skewered with buss bar.

Like I said I like my filaments twisted and flat to the chassis. I could say filaments should be seen and not heard but I don't think they should be seen, either. If I can tuck the filament string under the flange of the chassis or shoot them right down the corner of the chassis that's what I prefer.

I always wire filaments before anything else and I always take more time than I should making sure that's the last time I'll ever have to think about them.

update:

I ended up going for broke and replaced all four preamp sockets and filament windings. I just got done rewiring everything(!), but since I haven't eaten all day and dinner's almost ready, I may not get back to the beast until tomorrow. Then it'll be time to check voltages and what have you...
until then, thanks to all stay tuned for more

ahh, success! Filament leads were the culprit.
Thanks to everyone for their help and assistance. I hope this thread can be useful to somebody in the future. Now, back to some jammin'
