That tube might even be worth money on Ebay!

Thanks Allison for your info. Looks like another one for the trash can. I
figured that the tubes which I figured would do as much as 4CX250s would get
me to 300-500 watts SSB. Oh well we can't get lucky every time.

I have a Motorola amplifier from a working remote base. The only number I
can find TLD6612A on the PA deck. It is a two tube, conduction cooled
amplifier that was operating on 161 mhz. The tubes are 65-82282D02 (Eimac
8560AS I am told is the same tube). I would like to know if anyone has
converted one of these PAs to 2 meter SSB and any hints of how to do so. I
don't have the manual for the remote base or the PA.

Please reply to the group.

Thanks guys,

IF it's the one I remember just retune it. For SSB you will have to
run different bias and accept lower power. The original design ran
Class C FM and is totally unsuited for SSB without different bias.

As memory serves for FM that was either a 40 or 60W package and
for SSB you cant run that hard. Also the input power limit was very
low (well under 1W).
