Tubes for Drake

Garey Barrell <[EMAIL PROTECTED]> made an utterance to the drakelist gang  ----------------------------------------------------------------------  Eddy -
Nope, no cigar.......    
NO modifications are needed to either the T-4(any) or the TR-4(any) to use the 6GJ5s.
Pin 3 in the Drake 4 Line transmitters is the cathode of the final tubes. Pin 8 in the transmitters is grounded at the socket.
With 6JB6s, K is connected internally to Pin 3, and G3 is connectedinternally to Pin 8.
With 6GJ5s, K AND G3 are connected internally to Pin 3, AND there is _NO_ connection to Pin 8.
So everything works the same, except G3 is connected directly to K rather than via a 15 ohm and 3.3 ohm resistor.
The only difference is the interelectrode capacitance, which is small enough (0.5 pF) that the neutralization circuit is able to take care of it.
NOTE: RCA Tube Manual for Class A Operation states "G3 connected tocathode at socket".

What's been missing all along here, is the mandatory execution --- right  from the get-go --- of TWO crucial operations, i.e.:    (1) The wire from pin #8 to chassis ground at the final amplifier sockets in  the T4X must first be snipped, and,    (2) A new wire has to be added, jumpering pin #3 to pin #8 at both sockets.    What will be accomplished thusly is the following:    (1) The pin #3 cathode "break-out" of the 6GJ5 will now effectively be at  the pin #8-cum-pin #3 of the T4X socket, and,    (2) For better or worse, the suppressor grids of the 6GJ5 tubes will be at  the exact same potential as the cathodes (NOTE: is that an especially  good --- or bad --- thing?).    Failure to first execute the "...nip & tuck" at the sockets will leave the  current meter reading "zero" all the time, and the finals will be "on"  constantly...correct?    I wonder if it wouldn't be simpler to just re-wire the filaments for 12.6  VAC, & a pair of 12JB6's, Hi Hi!    ~73~ Eddy VE3CUI - VE3XZ

I found this big list of switch abbreviations (commonly used in lerg and other co info sources) that match up the switch type and manufacturer. It's pretty leet and I've never seen a list as complete as this before. Theres all kinds of cool switch types in here! Enjoy!
