The tube heater is blasted with excess voltage: I haven't noticed any heat issues at all. I always replace that with a brand new one unless the one which was already installed is spectacular..monitor audio bronze 2 yaqin vk 2100
Pio1980 , Mar 14, 2018. In a slightly different but related subject, I am also looking at adding inrush limiters to my tube type gear to help extend the life of the tubes by limiting the turn on current and allowing them to come up slowly.
Amazing how many are a couple of volts or so "off".
You will want a good 6AK6 for test. I've found that it's a lot easier to crack the glass envelope with a butane lighter.
The antenna couplers.. Do you think that it could have a noticeable impact on the performance of the regulator even after it's run for a while? I do plan on looking for a replacement 6C4 for the one that tested lower than the others. China's a long way off. Eastern Bamastan. Here are some tips to help you take advantage of shopping on the web the next time you need an goods item. Perhaps a small fan from.. These sites can be a real-time and money saver!
I know there will be more than one answer on this. Fix that rather than changing the RF amp! Wouldn't it make sense that a tube that started oscillating while shunted with 0. V207 appears in figures 23 and 75 of TM-11-856 and in figures 5 and 58 of TM-11-5820-358-35.
One needs to not burn up the grid so watch that grid current to keep the grid power within its power dissipation rating. The problem went away so, I swapped the caps and then the tubes in the decks and reinstalled the original deck.

They cut the phase noise by keeping the tuning range narrow and doing it at VHF then dividing down to the 5 MHz range. Has anyone else seen this before?
I guess I'd test more for the current range that was regulated. I always install the new tube on the IF deck. Do this test on your receiver and see the difference in 5749's.
