Hello All,
I am new to this list, but reading it for some time now.
I'm in the process of setting up/restoring/repairing a Drake 4C line:
R4C, I own this receiver for 35+ years, proved defective when I recently
switched it on after some years of storage
T4XC, bought recently, sold as being defective
MN4, working OK
MS4, working OK
AC4, currently being refurbished by me
As all items were bought separately, I'm missing bits here and there,
like the screws that mount the AC4 PSU in the MS4 cabinet from the
bottom side.
I assume they are non-metric (M3/M4 do not fit).
Can anybody here on this list please tell me what thread/size they are,
so I can order the right screws?
I could not find any info on this in the documentation.
I too have a second question.
With the AC4 came four spare tubes, supposedly usable as a replacement
for the 6JB6A power tube, type 6JF6
Is this a direct "drop-in" replacement for the 6JB6A in the Drake T4XC
or would I have to change (many-) things in the PA circuit
(neutrodynisation etc.) to be able to use these?
Any help appreciated.
73's,
Henry - PA0HJA
