For those who have old tube transmitters that used two 67 1/2 volt batteries to make 135 volts, you may have noticed that these batteries are no longer availlble in the same size, and the ones you can get are really expensive. Here is an ecconomical alternative if you want to fire your transmitter up and see it work:

Use fifteen 9 volt transistor batteries in series to make the 135 volts, it's just that easy. Buy a big pack of them at Costco.

Have fun at Octoberfest, wish I could make it, but it's too far from California.

Thats a good idea.
What we use to take for granted in the good-ol-days we now have to work something else.
Still have a old Orbit single channel.

I found a boat load of Burgess 30 volt batteries at local swap meet. The guy thought they were misprinted on lable and some other voltage at first. As a total, they cost less than one dollar each. He must have checked the one on top of the pile for it was down to about 15 volts. Rest OK and a good deal too.

I connect four up to get 120 volts. Instruction sheet says it will run OK down to 90 volts.
