Drake experts out there, I need help !
TR-3 SN 10892. Rcvr functions
fine on all bands.
Will not tune up in X-CW position.
No plate current,
thus no rf out.
BFO and mixer appear to work as I can get signal to another
receiver on proper freq.
Have good rf signal at plate of driver tube on a

Gary, I purchased your best CD from you and love it. However, I have a TR-4 C
that is serial number 23470, that has a different pc boad than any of your
pictures. It is adjacent to the VFO jones plug toward the filter cap. It has a
.02 cap along with a 100, 22K, and 330 ohm resistor. I have PTO

Anyone know where one can buy a new front panel for an L4-B amplifier ? I got
a good deal on it but the front panel has quite a few scatches. I also need the
high voltage scew in plug for the amp end of the hight voltage lead. Thanks,

That idea on the soldering iron is great. I forget mine all the time. It is
only 45 watts, but could still do some damage. My ham friend found out about
another great item. We have Steves Warehouses here in Oklahoma. For $19.95 you
can get one of those measuring wheels to measure your antenna

How about running the bias through the coil of an in line small relay. It is
held in any time the negative voltage is present. The present final cathode to
ground circuit would be run through the normally closed relay points. Loss of
any bias current and the relay cuts off the finals. Boyd
Your seller is rippng you off. I have sold on E-bay for many years and the
shipping information is via UPS, FEDEX, USPS, etc and is estimated by
furnishing the weight, dimensions, ship point, delivery point and special fees.
E-bay has nothing to do with the cost of shipping. They simply provide

Hi
Howard, If you will click on his user name and then click all feedback you will
notice he has a total sales of 10287 with 149 negative. He is known to display
some different pictures than the real thing. I have purchased an AC-4 from him
and it was ok. As long as the transformer is OK, you will
