UX5 adaptor for an AVO VCM-163

[Mike Diack]

I **KNOW** this is one helluva long shot, but if anyone has a spare UX5
adaptor for an AVO VCM-163 bottle tester, I'd like to buy it.
cheers

I have built a UX4 adaptor that plug into the Octal socket on a 163 to test
300B and 2A3 .
I use a old Octal base and solder thick solid wire to a UX4 socket. Pin 1 to
Pin 1, Pin2 to pin 2 etc. The setting to use is the same as in the valve
data manual. You
should be able to build one the same way for the UX5 or anything else.

Dear Mike

Adapters are quite easy to assemble if you start with the right parts.
I make 807 >> 6L6 adapters using octal tube bases and Amphenol 'S'
series ring mount tube sockets. These are the type without a mounting
flange, that are held in place with a wavy springy-thingy. For this
application you won't need the mounting clip. These sockets are an
exact fit in the top of some octal tube bases. I use AWV bases, older
RCA tubes are the same size as well. Not all octal tubes have all
eight pins fitted, pin one is frequently omitted. So when you have
found the right type, smash it and use a solder sucker to remove all
the solder from the inside of each pin. Scrape out any crusty brown
goo from the inside. Solder bare wires about 10 cm long to each
contact in the UX5 socket. Make the wires this long so you can pull
them tight through the holes in the octal base. Thread these wires
through the appropriate pins in the octal tube base. At this stage
the wires aren't yet soldered to the pins. Double check the wiring.
Ease the socket slightly out of the base shell just enough to apply
adhesive. Then tug on the wires that pass through the pins to pull the
socket in and take up any slack. The wires are then soldered to the
base shell pins and trimmed flush. Another check for correct wiring
and shorts and it's all ready to go. If a mistake or short exists it's
best to start over, kinda hard to salvage once the adhesive is in.
