[Amps] More Clipperton L

[Alek Petkovic <vk6apk@eon.net.au>]

G'day Ampers,

I had a couple of spare hours today to play with the Dentron Clipperton L 
amp I mentioned a few days ago.

I measured the filament volts at the socket pins. 7.32 Volts was the result!

With a combination of resistors in line, (7 x 0.47 Ohm/5w WW in parallel) I 
now have it set to 6.15 Volts with 245 Volts on the mains. Hopefully that 
will keep the new tubes happy.

I guess it was not surprising that the 572B's which came with the amp were 
dead flat. Funny enough, they were probably the original tubes. They are 
marked Dentron, all with 7850 date codes.

To answer Rich's last question on the subject of the tubes' demise, no, 
there are no shorts in any tubes. None that I could measure with an ohm 
meter anyway.

73 and thanks
Alek. VK6APK
