Tom,
The complete part number of the Motorola M9760 transistor is 4800869760
which, unfortunately, has been discontinued. Please advise the model number
of your preamp, because the transistor shown in the parts list for the VHF
preamplifier is M9730- which is also discontinued. I am using this
i
numbers that is
stamped along the cable, and we may be able to identify what product you
have.

If your fans are audible (to the ear) across the room, they are probably
running far faster than is necessary for cooling.

Sure enough, a tiny crack had opened on a PA power lead. Reflowing solder
at that connection cured the problem.

Tim,
Scratch and claw no longer. Marlin P. Jones has just what you want, for 20
bucks each. I just bought two of them. Go here:

than risk the auction source, just call up one of the regular vendors- or
even a local radio shop- and offer to buy just the radio end of a Micor
cable with two feet or so of cable connected. I did that a few years ago
and paid five bucks each, with free shipping.

during normal operation, and you must
replace this capacitor with a similar unit designed for this application.

f it blows, either the transformer or the capacitor is bad.

measurements?

Laryn,
The diode part number is 19A116524P2, which is available from New London
Technology for $6 each. The commercial equivalent is a 1N2158R diode,
according to LBI-30867F.

Tom,
A battery that has sulphated is damaged, and can rarely be returned to 100%
capacity, regardless of advertizing hype. Unless the battery is for a
low-risk application, such as a trolling motor or golf cart, turn it in to a
recycler and buy a new battery that you can depend upon.
73, Eric
Joe,
You should be specific about your needs. Some Micor reeds are thin and some
are fat- and won't fit in some radios. What part numbers do you need?

Chris,
The 4EX12A12 Test Adaptor is used to facilitate the testing of GE portable
(personal) radios in the MPI, PE, PY, MPR, MPX, and Marc V series. The unit
does nothing more than provide an audio input and output, a speaker, and a
PTT switch. You will need the appropriate interface cables to m
Don,
It appears that only the even-numbered pages were scanned. Perhaps Skipp
can help rectify this oversight. This is a valuable document, and Skipp's
work is very much appreciated!
