Re: can you identify this rumored to be tek part?
John, those look like 7A19 fuse or attenuator elements. See photos on Tekwiki, or I can take one apart when I get home from work. https://w140.com/tekwiki/wiki/7A19 thanks, Adam

FREE: Spare NFM (Jared Cabot?) peak to peak detector PCBs (067-0625-00 equivalent)
I have a few of NFM's Peak to Peak (067-0625-00 clone) PCBs if anyone would like one for free. I only needed one for myself to play around with. https://youtu.be/VVPHifwseJc?si=BO3K54p_2KfN1lOO msg me

Re: Nothing built like Tektronix, period!
Radu, you are always exceedingly polite! I¡¯m surprised you had difficulty working on a Wavetek generator. I repaired my model 166 function generator about 8 years ago, and I don¡¯t remember it

Re: Slightly OT: Question on commercial PCBs (such as PC computer motherboards) vs "one off" or prototype PCBs (Oshpark / JLCPCB)
The smell in the welders was evident on brand new units and replacement PCB's Over time it went away. Other brands from Europe (Kemppi, ESAB, etc), Australia (Cigweld) and USA (Lincoln) didn't have

Re: Nothing built like Tektronix, period!
I have the same experience with some Waveteks - a sweep/signal generator in my case - and working on it has not been fun. Furthermore, I think the design was fundamentally less than stellar (to be

Nothing built like Tektronix, period!
Today, was trying to fix a Wiltron 610D sweep generator with no output. Opening it up revealed the very difficult path to just accessing any of their boards. No slack in connecting wires, no way to

Re: Extra Tektronix 155-0019-00 part (free)
Yes, my address is good in QRZ. I'll certainly pass it on if someone needs it before I do (and I hope I never do but...). Thanks! Barry - N4BUQ

Re: Extra Tektronix 155-0019-00 part (free)
How about I send it your way, with the promise that you'll pass it along if someone needs it before you do? Is your address good in QRZ? If so, I'll pop it in the mail. 73, --- Zach

Re: Looking for rear feet for 2465 DVM scope
I've tried DC balance. I was mistaken on the channel 2 waveform on GND. It's on AC. I have it set right now at 2 mVAC and 2 nS on channel 2 with no probes connected and readout on frequency is 850 MHz

Re: Tektronix 547 Lack of Sweep or Intensity Control
Gordon, If you have a crt checker, you may be able to test the crt for leakage and 'blow' the short by the rejuvenate part. If not, you need to find another crt. I would like to find a P11 for my

Re: Tektronix 547 Lack of Sweep or Intensity Control
Thanks Morris. I must admit the thought of an internal crt fault crossed my mind. I will re-check it to be sure I wasn't seeing things. I will also check the crt pins and plug as you suggest. Gordon

Re: Tektronix 547 Lack of Sweep or Intensity Control
I'm sorry to have break some bad news but it looks like you may have a grid-cathode short, or at least leakage, in the CRT. Either way there should not be HV on the grid if you have isolated it by

Re: Slightly OT: Question on commercial PCBs (such as PC computer motherboards) vs "one off" or prototype PCBs (Oshpark / JLCPCB)
It could be. But welding machines get hot. And so, that drives out VOCs that wouldn't normally be driven out in such concentrations, at room temperature. Likely to me... unless you microwave your

Yeah, the older types with the hidden screws are a right pain in the bum, and the countersunk screws puts outwards pressure on the plastic right at the thin corners which makes the corners crack worse

WTB: P6245 probe, but just the probe end....
Hi, I recently picked up a faulty P6245 probe, mainly for the accessories that came with it. It looks like someone blasted it past it's ratings and blew a chip in the probe end, but I'm thinking it
