Another marine radio has been returned to the airwaves, thanks to the 
same method.  I've done two of the Hudson American marine 
radiotelephones now, because they met my primary criteria:   "they 
looked cool".   The company clearly invested in some industrial design 
services to make the styling of their products appealing to boat owners, 
even for the low-end two-channel "Privateer" that I used on the AM net 
today.   I've added pics of the radio after modification:

Since I only wanted the 75 meter AM band, I used inexpensive N4ESS 
crystals for transmit, and the Epson oscillators in my Four Channel 
board for the receive side.   Simply connecting the output of the board 
to the oscillator grid pin of the 7A8 converter tube via a .001 uf 
capacitor is all that was needed, but I also rewired the old crystal 
switch to provide a ground to the board for channel selection.  With 
it's three-tube transmitter (including modulator) makiing 6 watts out 
and four tube superhet receiver, the Privateer is as sweet a little 
receiver-transmitter as you'll find!
