I put a 50K 10 watt resistor across my fuse in the fil. C.T. so the bias is at cut off if it ever blows. Tony King - W4ZT <w4zt-060920@...> wrote: pentalab wrote: I'd protect this with diodes and

Fellows I have several fuses installed in most of these linear's. Like a fast 750 ma 3agc style grid fuse... located between chassis.. and negative terminal of 0-1 Amp grid meter. Also have a 3 A

The V-drops across the cathode resistors is what helps to equalize the cathode currents in the 4, 811As. However, 4, individual bifilar filament chokes and 4. DC blocker/coupling caps are needed.

Gents A few years back... after consulting with John Lyles about my idea, I decided to try it... it works ! Nothing really new here... but thought I'd pass along this info... since you will never see

I guess i need 8 resistors? but, how about the voltage drop over the resistors? or should the resistors be so small that I don't need to worry about that? Since i have about 75 ohm input impedance, do

Just in case anybody is interested.... RF Parts has a sale on MANY of their tubes.... both triodes... + tetrodes. eg- Svetlana 3CX-3000A7 $695.00 Svetlana 3CX-6000A7 $855.00 [reg $975.00] ! Of course
