Maybe I'm wrong here but I think he wants to know if it's possible and would account for why his older one might have lower hours than his newer one...suspecting that possibly someone already reset th

Thanks for sharing this. I subscribed and just watched a few of these, including the Tektronix Printed Circuit Boards 1969 video. I was one year old when that video was made. It's simply amazing to se

Chris Pierce, It is NOT you! The issue is with Chris Johnson's email. You are Chris Pierce. Chris Johnson managed to get his email hacked. Not you. If you are not Chris Johnson you can ignore this but

I made and saved a pdf copy of that 465 cap replacement guide a while back. I've uploaded it to the group. It's not mine, but was written by Ron Childress-October 2008 and I've left that info at the t

I also have a 475. Most of those listed are the big blue filter caps. It was recommended to me by this group not to mess with those unless they are definitely bad. It's easy to damage the board and it

Roger, I had very little scope knowledge and didn't need another hobby either. Like you, I fix EVERYTHING in a house full of girls (four daughters ages 10-21) and it keeps me pretty busy--cell phones,

Up until 3 years ago I lived in the PNW (Klamath Falls, OR) and shopped at Fred Meyer all the time. I now live out in Charlotte, NC, and I can tell you that there is no store out this way that is like

I'll also reply to the group with this tidbit of info I recently found that might be helpful to anyone not aware of it... I realize it's not helpful for the modules themselves but you can get free OEM

JimMC, Hope you don't mind my basic question. How are you measuring the ignition waveforms? Are you using a current clamp or some other method? I've been wanting to do this but don't really want to bu

Chris, Not sure it's the best scope for the job but I've been attempting a bit of this with my 314. It runs off either 12, 24VDC or 110-220VAC but does not have an internal battery. The storage featur

I believe it was mentioned that, for now, posting is disabled as it's just a backup in case something happens to Yahoo. That wasn't mentioned in the welcome email I got from Groups.io, though, so that

If it's slipping on the shaft you'll have to dig in a bit to get to that board. I removed the same board on my 475 not too long back in order to replace a failed timing resistor and it's buried a litt

So noted. I didn't have my meter opened up, nor the parts list handy. I just went by the manual but mistakenly omitted the "k". Whatever resistor R25 is, apparently a 27k, disconnecting it does cause

Kevin, I think you're missing the boat here. I, and many others, have received LOADS of help from this group but, just as a common courtesy, you have to provide them the info they need to help you. Th

Thanks Steve! Now I feel vindicated for also buying the Anatek Blue ESR meter! It was a bit expensive but I like it and had fun putting the kit together. I didn't get as deep into it as changing the d

Kevin, Because of the thread over at antiqueforums.com I think there may be some confusion here that needs to be cleared up. There is SUPERB help here but you have to give them good info and take thin

I'm not sure how relevant this is but Kevin also has a thread going over at the antiqueradio.com forums and someone there had him check the power supply rails with an ohm meter. His +55v rail measures
