My message to Dan Rea are bouncing, so please forgive the BW:
Dan,
Hang fire please - I just got this baby hooked up and there's been some
creative wire cutting done.
The supplies for the CRT have been cut at the trafo.
It needs lots of TLC as its not actually working right now - fun ahead.

Dave,
I have a complete 527A with a slightly screwed up case (someone removed
the handles and smoothed the edges!) that was working when I last used
it about 6 years ago. The crt at the time was good and working. I had
planned to put it on ebay but never got around to it. Email me off list
if
A suggestion.
$300 does seem a lot for a gamble.
But if it really gets bad you can buy any scope and plumb it in and get
what you need.
Clearly an OK answer. But a thought none the less.

A little extra heater voltage and allowing the tube to 'cook' a while can
help as can a CRT rejuvenator but the cathode is usually tiny on a mono
tube and from experience with television repairs back in the dawn of my
career, they very rarely last any length of time after rejuvenation before

Hi:
Yes, there are Cathode "Rejuvenators" that can sometimes give a CRT some more lift. This is a problem with all test
equipment that uses CRTs. There are LCD replacements for the CRT in some HP equipment, like the 8566 SA.

Hello to the group.
I was not going to comment on the thread. But realized I should.
A caution on CRTs is that if they have been around a long time they may
have very poor emissions. Even if new. Cathode pollutes over time.
Just saying don't be to surprised if you don't get what you paid for.

Not rare but uncommon. I gave the one I have away a couple years ago. Ask
on a few of he military/boatanchor lists, I've had pretty good luck.

Trying a long shot here, I'm looking for a 1" CRT type 1EP1 (or 1EP11, or?)
for a Tracor 527A Frequency Difference Meter.
I did spot some on eBay but the vendor had a rather high opinion of their
worth :) at over 300 dollars
Anyone got one to spare?
Thanks
Dave
