Since you guys were talking about D VOM and A VOM meters, I just recently picked up this seco model HC8 cathode current meter. Its the best thing next to the scope! Basically, just remove the HO tube, plug in the appropriate socket, and plug the HO into it (its a socket in series with the tube) and you can measure cathode current right off the bat. No unsoldering leads etc etc. The meter gives current figures for all the different HO tubes. Very handy. It was given to me by my local service shop. I think all of use should have one of these!

That reminds me, Doug. I'll have to stop by the local Radio Shack one of these days and get a new VOM (I left my Micronta digital, along with two tool boxes and more spare parts than you could shake a stick at [!], back at my former home [in the basement] before I moved). I've had to rebuild my toolbox since I moved here, still have some things to get before I can say I'm done with the job, but it's not going to be as bad as it has been.



That Seco cathode current meter is an interesting piece of test gear, which I'm sure made it a lot easier for TV techs in the '50s and '60s to measure the cathode current of the horizontal output tube in TVs of that era (beats the pants off physically breaking the cathode circuit or any of the other dodges techs used to use to measure HO cathode current, that's for sure--the only one more simple than that was to use an adapter under the HO tube, between the tube base and the socket). I never saw anything like it before now, and I worked with electronics as a hobby for over 30 years (now more into ham radio, old small broadcast receivers and computers since moving to my apartment in a small town four years ago, but I still like reading all the posts [and seeing the pics of your old sets] from you guys who are still collecting old TVs like I did in the '70s. It always brings back fond memories).

I'm glad I am a member of AK. You fellows--and the guys in the amateur radio club I belong to--are the greatest! Don't know why I waited so long to join AK, but no matter--it was well worth the wait. You can bet I'll be staying with AK for a while.


Kind regards,
