Scott,
I have the twins and the supply. Although not looking to sell, I thought I
would say "Hi" and let you know what I have found. My transmitter also does
about 20 Watts, and the plate modulation seems rather "ratty". My twins also
need some work. The manuals I have show a different version of the
transmitter. I have the older version transmitter. Modulator tubes
orientation is different, as well as a few other things. This makes it a bit
difficult to work on, but that's the fun. I'm looking for the MOBILE DC-DC
converter for the twins! If you see it anywhere, buy it for yourself, or let
me know and I'll buy it,or I will probably use a heathkit DC-DC supply, the
voltages should be close enough. I'll look for another AC supply for you.
Good luck,
George AB2KC

Good morning!  I'm looking to buy a Morrow RTS-600S AC power supply and
built in speaker which powers both the Morrow
twins, MBR-5 receiver and MB-560 transmitter.

I connected up the MBR-5 and MB-560 this weekend using a homebrew supply
that came with the radio.   I think the receiver is pretty sensitive, it
sounds nice on cw, is a bit broad on AM as I think the bandpass covers the
entire AM window on 75 :^)     The transmitter outputs only 15 - 20 watts so
I need to look into that.  I will be ordering some manuals for it today.
This will be a fun rig to run on 10 and 75 AM!

If you have one for sale, perhaps you know of one or can provide a lead on
one.  Thanks!

73,  Scott WA9WFA
