[WRL] 755A VFO and other matters.

[Kenneth G. Gordon]

I have a WRL-755A VFO which was given to me some time ago. 

It arrived all in one piece and in pretty good condition. The screws holding the 
chassis into the cabinet had been removed, as also had two of the four 
screws holding the box on top of the chassis. There was a note attached to 
the top warning that the chassis was loose.

In any case, several years later (yesterday) I fired it up and examined it pretty 
closely.

Quite obviously, the reason the previous owner had opened it up is because 
the VFO is very unstable. It acts as though something is not making good 
contact somewhere.

I have examined the thing fairly closely, and by now I suspect that the riveted 
tube sockets and ground connections are not making good contact. I am 
thinking about getting out my big soldering iron and soldering all those 
directly to the steel chassis.

Once, after peening one of the rivets, the VFO remained on and steady for 
over an hour.

Has anyone else experienced anything similar to this? if so, what was your 
solution?

Someone loaned me a 755 VFO about 60 years ago, and I thought it was 
wonderful.

This one is somewhat less so, dang it. I would like to use this with a DX-35 
(my first transmitter in 1956) in the next CX, but I would much prefer it to 
work properly.

The only other VFO I have always wanted was a WRL V-10.
