Another CTC-10 Montecello! (in Philly this time)

[holmesuser01]

My CTC-10 has that same VHF tuner knob. I need one, as mine is cracked where it fits over the tuner shaft. Since my set came with no knobs, it matters not if it is slightly different. My knobs all came from an 11 anyway.

Is there a difference between the 10 and the 11, other than tuner, and CRT choice?

Living room square footage must have been cheap (and plentiful) back then. This cabinet is very similar in design and probably size as well to the Monticello I picked up last week. Apparently this tuning knob is a high failure part as mine is cracked where it fits over the tuner shaft too. A loose fit but it does the job for now.

I read with interest the reference to “waking up” the CRT. Is there a thread covering this subject? I would like to know more about the process.

Operating a CRT filament at rated voltage for extended periods (days at a time) will sometimes bring a 'sleepy' CRT back to full emissions, which is what I usually try before heading into the cleaning or rejuvination modes on testers. The theory is the cathodes lose some emissive capability after not being operated for a few decades, so getting the cathodes good and hot for a while will sometimes bring a seemingly dead tube back to life. Regular use typically makes them better with time as well, though it's a 50/50 shot. Seems to me most tubes from that time were ran into the ground though, I have 3 duds in my bedroom right now that won't come back no matter how many times I rejuve them. Shame too, a 21CYP22A I have has perfect emission on 2 guns, but blue is totally defunct.

Thanks Steve !!

PS (I just ordered a NOS tuning knob for my set from Moyers.)
