BK B & K Precision 467

Post by Ekco-scott » Mon Apr 06, 2015 5:46 pm

Hi everyone long time no post hope you are all well :)

I have just been offered a BK B & K Precision 467 CRT tester and I was wondering if it can be used on black and white CRTS as from what ive seen on line its for colour. I only restore b/w sets so it may be of no use to me ttt:

Thanks in advance

You certainly can use it on B&W, the "red" meter is used on it's own for mono emission reading. I use one myself. :)

These are good testers, I have 2 here! Well, one's broke...

For testing a CRM92, you'll need to make up an adapter, I'm sure someone's covered that subject on here before. Also, some black and white tubes read low on these testers, when in fact they are OK. I had this on an Ekco set I was working on, the tester read it as in the red, and only just made it into the yellow after a clean and balance, but the tube was actually really quite good once the set was working!

Regards,
Lloyd

I have both a 475 and a 470, neither will test triode tubes such as the CRM92.

Nope, B&Ks don't 'do' triodes. They need a minimum of a tetrode gun to function because the control grid is held negative w.r.t. the cathode when testing: for older tubes you are much better off with a 'Radar' tester: either the original one of the later 202. Both can happily supply the 2.5A needed for some CRT heaters as well.

There is also at least 1 version of the Beamec that has a triode/pentode-tetrode switch.

I am in the process of making up a lead to enable my Taylor 45A Valve tester to test triode CRT's, I have the test settings in the valve data books.
I have already wired an octal plug, just waiting for some mini croc clips for the CRT end.

I would like to get hold of a Radar or Beamec tester at some point, but adding the lead to the Taylor will do for now.
