Here are some items for sale.  Prices do not include shipping unless 
stated.  I will ship overseas.

McMurdo Silver 904 Capacitance Resistance Bridge....$35 plus shipping
This is from the late 1940's. The tubes are good and the eye tube opens 
and closes however, I can't vouch for accuracy as it still has all of 
the original capacitors inside. This is a neat unit if you collect 
McMurdo Silver gear.

General Electric RF Ammeter - 4 Amp Maximum........$25 plus shipping
The meter reads 0-4 amp and is in a metal enclosure with SO-239 
connectors. This is a tested and working meter. I use these to tune 
vertical antenna arrays by matching the RF currents at the base of the 
antenna.

electrolytics and and plays with no hum but he volume is low. The rest 
of the radio needs to be re-capped.
