Radio Restoration Needs


Vacuum Tubes needed as spares aboard the WWII submarine USS COBIA (SS-245).


If you have any of these tubes please consider donating them to the

Wisconsin Maritime Museum
75 Maritime Dr.
Manitowoc, Wisconsin  54220
Attn:  Electronics Shop

Your donation will help support the ongoing restoration and operation of
the radio and radar equipment on the boat.

Send an email to museum@wisconsinmaritime.org with "vacuum tubes" in the
subject line if you have questions.


NOS tubes are desired but used tubes, testing "good", are welcome!
