I agree completely with Don's opinion and don't want this question to in 
any way disparage the unit he has available, but I seem to have trouble 
with the one I have been using for a number of years.  It was made for 
TMC by RCA Ltd. of Montreal, and is badged as CU-5069/FRD-10A(V), but 
the manual supplied was for the TMC AMC-32 which seems to be identical.

For no apparent reason, an output will go dead, even though I haven't 
done anything to cause it.  Once or twice I will admit I've keyed a 
transmitter into an output, which of course destroys the transistor, but 
even after eliminating any and all connections to a transceiver, I've 
still got several dead outputs again, after going through the unit a 
couple of years ago and replacing dead transistors (with new heat sink 
grease).

If anyone has experienced this and can offer any suggestions I'd welcome 
them.  The only thing I've found is the addition of cooling fans per 
this article: http://www.skirrow.org/Boatanchors/TechTalk6.pdf       
Also looking for a source of reasonably priced 2N3866s.

The multicoupler is the perfect way to have multiple receivers available 
and really a nice piece of equipment.

Thanks and 73,
