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

[droptop]

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.)
