The input (loop thru) signals J10 and J12 are 10k from another pin, "O". The output signals at 16k and a diode drop away from another pin ("J" ->- J15 or J16 ->- "M"). I feel like this should be

For my fading problem I think I have narrowed things down to electrolytic (or is it wet tantalum?) caps, C4327 5uF 150V, and C4006 4.7uF 35v (leaked some). C4327 was arcing sometimes when powering on!

output on reading dead. How did you check for a change in resistance, Dennis? Craig

Inside the S6 Sampling Head there are 3 PC boards. One connects to the socket inside the 7S12, and nothing else. One is the strobe board, and the third is the preamp board. They are interconnected in

$100 for a 067-0587-02 calibration plug in is a steal. Craig

my scope has the vacuum tube rectifiers - I am pretty sure the CRT is OK because I have gotten it to run for a bit and it makes a fine display. For now, I'm inclined to blame caps - specifically the

I saw that pallet; I think there's a 323 in there.

The contact's name is Volker Klocke at oscilloscopemuseum at gmail dot com. Located in Western MA, I've never visited it.

Wow!? I haven't seen a pallet like that since I bought my two.? I'm SO glad I'm not closer! -Dave To: [email protected]; Dennis Tillman W7PF <dennis@...> Sent: Thursday, June 14, 2018

BTW... just up the road from Shannon is a full pallet of Tektronix stuff. https://nh.craigslist.org/ele/d/tektronix-oscilloscope-lot/6610266987.html

Finally got this thing fixed. Looks like someone attempted to repair a bridge rectifier and during the process tore out the through hole plating. I'm going to order some eyelets and a staking tool

Hi Shannon, I was not aware of this museum until you mentioned it. Where are they located and who is their contact in the US? Dennis

Thanks, decided to donate a 555 and a 536 to oscilloscopemuseum.com .

I don't have a sampling head, let alone one with sticker residue. So to validate @Dennis' results (not that we should have any reason to doubt Dennis...we absolutely shouldn't), I used Goo Gone on my

Sand CAREFULLY to remove the rough edges fill with grey auto body glazing compound. Wet Sand with 400 wet paper to smooth to touch and paint with either Testors Silver or Floquil ‘Platinum Mist’

Hi Shannon, It’s good to hear from you again. I hope all is well. Dennis Tillman W7PF

Thank you for all your great suggestions for removing sticker residue and warnings about what to avoid. What an astounding variety of responses about how to remove the sticker residue without harming

Search for xyzzy in the listing body. Thinning the herd, several working scopes for $100; along with some HP and GenRad gear.

I use W-D40, it works great. It does not harm the paint! wrote:
