FOR SALE: E.F. Johnson Viking II Transmitter

Runs about 120 watts out on AM and CW with two 6146 RF final tubes.
Covers 160m through 10m bands. Has a ten position crystal selector 
switch or use with external VFO.

This fine old AM-CW transmitter is missing the top cover and needs 
a new AC power cord.  It has not been gone through or restored, but 
will clean up very nicely.  All the tubes are here. The main components 
are all there and look to be in good condition. This rig is built like a tank. 
It's also very simple to work on and understand. 

Crystals available, or use with a VFO. Comes with a copy of the manual.

Available for $235.00 plus shipping

Looking for a Dumont 274a manual or schematic.  It is about the most basic 
scope but has had some work done on it and I'd like to make sure the right 
parts are there.

Subject: [DCboatanchors] National Calibrator XCU-50-2 (For HRO 60) problem
Message-ID: <59CBBAFC516F46DEA6C729E6C9D1D92B@ASP>

As part of the resurrection of my Dad's HRO-60 I've found that the 
calibrator only works on the 1 Mc side.  The 100 KHz side appears to be 
dead.

Has anyone seen this anomaly before.

I've already

1) changed the tube
2) changed the bypass caps
3) replaced the 470K resistor that had wandered up in value.

Thought I would ask before measuring the low-value caps or sweeping the 
crystal.
