I enjoyed your microscope review. They have improved the stand since I bought the one I have. Thanks for watching and taking time to leave a comment. If you ever need anything from the U.K. etc like a radio I will send one over. Best regards Chris
Unfortunately I found the AVO components bridge has quite a lot of components missing and not easy to replace. I looking for another unit as spares. Thanks for watching regards Chris
I love old Taylor test gear, I recently got my 65B to match my 45A valve tester, which I prefer to my Avo! Certainly a real steal for £7, hope to see some more videos on all these goodies 👍
I may do the Advance RMS meter next. Unfortunately the AVO bridge has some parts missing internally and they cannot be easily replaced. Thanks for watching best regards Chris
Hi Chris!! Great to see you on tube once again. I remember seeing that generator alright! Great bargains to be had. I think the damp gets into the windings in the coils, upsetting the Q and inductance, pulling the frequency off. I'm sure you'll be able to pull it back on point.
@@fredflintstone1 Yes you are right but the doobrie is a part that was lost two weeks ago and the vaccume cleaner bag is empty so there is no hope for it. Whatsit is a faded memory that can't quite imagine the shape but you seem to think it must have been painted green, but you don't like green... ahh your memory is trying to help you :-D Sometimes the shape can be painted to match the carpet, then you are in trouble. What a load of cobblers.... i have shoes to be repaired..............
Happy to see you are back, Chris! What a beautiful old generator - I for one would love to see it cleaned up and calibrated. My current project is a much newer Wavetek 2407 signal generator - on it's way back from the dead. Regards, David
Great presentation as always Chris - that's quite a haul for just £7. That Taylor dial is indeed a thing of beauty. I do think you've some work on tweaking that back to spec, worth doing though, just so you can silence the Spiers... Looking forward to the next one.
Im good thanks. Just been stupid busy at work due to massive component shortages having to modify designs for alternative and tweak firmware. Also just been trying to cut down on my internet time. I spend more time watching videos than I do in the workshop. Just not enough hours in a day. Glad to see your keeping busy.
Glad I saw you here finally Chris instead of on a milk carton or getting into a crash in a RUclips Dashcam video. Then I would have worried. The Advac 77A RMS meter aka AC Voltmeter has Hunts capacitors in it. Troublesome buggers that must be replaced. The Taylor 65B is from 1942 but is well designed for testing receivers. Yes you should do a calibration on it.
Yes I will try and do the calibration. The Advac is a nice little meter I probably will repair it but don’t have much use for it. Good to be back and thanks for watching and funny LOL comments
Great video Chris. Very informative as usual I would definitely like to see the Advance VTVM investigated and would love to see the calibration of the Taylor sig gen. Cheers Graham
I was wondering where you had got to! That Signal Generator is lovely and looks good too. I wonder if it is the valve.... And yes get it working fully. Should not be too hard.... and everything can be fixed if you spend the time.
What a nice generator, it's solid and very little to go wrong. Well made and a loverly round window frequency scale. Lots of knobs to play with, ooow naughty :-D That metal band looks reliable. The multimeter looks interesting, you can never have enough meters. Then you can drive yourself mad (madder) trying to get all your meters to agree :-D Good video chris, thank you and fix the generator first, what did you say ahh bugger off :)
Calibration!! I think someone did a guide to which coil is what on UKVRR. It does seem more out than it should be, certainly compared to the Advance equivalent service generators. Taylor must have knocked thousands of these out going by the number of survivors.
Great video Chris I think I'm going to book a night out in Barnsley soon now ! Laughing about the Y safety caps , if you can't see it doesn't exist , bang on Them glass fibre pens are good for cleaning green contacts The plastic covered caps probably have a metal inner case , might be just the plastic that has perished ? I know I'm the optermist I've heard putting one hand in ya back pocket is a good idea working on live chassis but I think your safety risk assessment is wood bead worthy Great to see you back uploading, similar I do more in winter months than summer, you wealth of experience is always a great learning curve for me and the way you moderately present it is fantastic "Was it mild mannered janitor....." was it the modern transistor radio that was out or was it the signal generator or was it the scope .. (Grin) Sometimes it's like the guy with a thousand watches who doesn't know what time it is Sorry for waffling, brilliant work Looking forward to seeing your next Best regards Shaun
Do you know the characteristic impedance of the generator? Terminating the output with the proper impedance might clean up the signal a little. But, in my experience, generators of this era tended to produce distorted outputs, so it might not make much improvement with proper termination. I have a US military AN/URM-25D (similar frequency range, which was definitely intended for communications receiver maintenance and alignment), which is a pretty good generator, for the era in which it was made (1950’s - 1960’s), and it has some slight distortion problems. They don’t appear to affect its serviceability, though. The AN/URM-25 has a calibrated attenuator, so that you can check receiver sensitivity, and it must be terminated correctly for the attenuator to be accurate.
I did try a 75 ohm matching pad whilst recording the video but it loaded the output very heavily. These were only service grade products unlike the stuff by Marconi but they were good enough to do the job. I have a number of specialists test sets I use for actual performance monitoring. Thanks for watching and taking the time to leave such a great comment. Best regards Chris
Chris, Terminating the output in the characteristic impedance will significantly lower the measured output voltage. This is because the internal impedance of the generator, and the terminating resistance form a voltage divider, each dropping half of the voltage. However, since the terminated output is usually connected to an impedance much higher than that of the termination, the error introduced will be small, and except for really fiddly precise measurements, this impact can be neglected. This does provide a relatively stable signal level to whatever is under test, making reasonably accurate sensitivity measurement possible. Regards, Gar
I’m good just stupid busy. Component shortages have to constantly redesign boards and tweaks to software. I kind of enjoy working on the vintage stuff as it makes a change.

Hello David I have repaired a few waveteks in the past they normally very well constructed. Not sure what I’m doing next.

I’m hoping the Taylor calibration can be improved it’s quite a way out. Not sure what will be on the bench next.
These should make for some fine future videos. Cheers!
Good to see you back, we missed your vids. I'd like to see if you could tweak this sig gen to be more accurate.
Hello Trevor. Yes hoping it will come a bit closer. I don’t think these were great performers from other examples I have seen.
Happy new year Chris, all the best for 2023 from me 😊
