Question re TL 922 amplifier
"Uncle Peter" wrote in message ... "bob.martin" wrote in message ... " and after lunch the problem had returned and this time is persisting despite removal of the valve. I haven't yet tried the mains blast across the pins as I'm not that confident! e advice Jim G7NKS You can use a charged cap to "blast" the short, might be less dramatic than the unlimited current behind the mains.. This sometimes vaporizes part of the grid structure and affects tube operation.. Pete Well done to you all,it's nice to see real amateur radio for once on this board.More of it please Keith. |
