order if desired.

have problems with the physical size of any tube substitutes, it may be
worth a call to AES to see if they have a brand that will fit.

still run into one of them from time to time. A pair of VF-1s make a nice
set of nostalgia bookends, but that's about the extent of their usefulness.

that depends on
the 10V line off. As I mentioned in a previous email, the real solution to
that repeating problem is to replace the adjustment pots on the power supply
board with multi-turn Bourns pots which won't change value when bumped or
vibrated.

(one per pot) located near
each pot position must be relocated to the back of the board to make room
for the pots.

the right height. Before ordering, take everything off of one of the
terminals and measure the height.
My caps have been running several hours per day for a couple of years with
no problems. I may be able to dig out a receipt if you have problems
locating a replacement.

from zero beat until the clicks were no
longer heard, and noted the signal strength at points along the way. The fixes
made a tremendous reduction in the clicks, with the remaining click bandwidth
no greater than that of my 781.
Best of luck!

The sensitivity of the TR7 is certainly lacking on the higher bands and a

problem with an outboard DDS VFO which has served me quite well for a while

. Apparently that's
been standardized over the years so any headset can plug into any aircraft
radio (at least for private planes). Whether or not that started before Drake
began using the smaller plug, I don't know.
