I agree about the soclets. I just fought a battle with a modulator using PP 811. Seems like other time I fired it up one of the 811s would be dark. Repeated 'fiddling with the socket' made it reliable - at least for now. HI.
But on the chance it is actually an intermittant connection at the filament lead, I would remove the base and 'brighten' the lead with steel wool or sandpaper before soldering. de KA4JVY Mark --- "A.R.S. - W5AMI" <[EMAIL PROTECTED]> wrote: > On 12/26/06, Bill Fondren <[EMAIL PROTECTED]> wrote: > > This may seem to be a simple question but I have a 100th modulator tube > that has a intermittent filament pin.
