From: N_Cook on 15 Jul 2010 06:20 Well that is what Avo calls it, I've never come across one before. ECC83 with curious cyclic swirling breaking-surf whitish-noise and clicks. Putting on Avo 160 tester showed <>short in A/R setting, I've never had before, A/R here stands for cold checking Anodes To Remaining electrodes. DVM cold resistance checking pin to pin showed about 9K between an anode and its grid. I will replace it but is there any point in blasting with some high voltage to vaporize whatever is bridging, for a known unreliable/short-term spare. I'm aware that a valve with leaky C to H, then running the valve with 10 or 12V on the heaters insted of 6.3V so they glow like bulbs for a few seconds, will knock back the bridging deposit for a few months or even years.

Used to do that with a TV CRT rejuvenator. It had a specific function to remove shorts. Sometimes worked, sometimes didn't. -- Altopia.com $12/m 10 unlimited connections
