577-D1 CRT phosphor
Yes, and some Tektronix cameras could mount a pre-fogging device, using red LEDs to 'flash' the film before, during, or after exposure. Could double the ASA of Polaroid (r) 3000 Tim P

Help on illusive sweep switching fault Tektronix 547
Just a thought, but are the two screws holding the 'B' sub-chassis tight ? There are two single-pin connectors nearby. best regards Tim

Things to include when asking a repair question

Tek style tiered knobs
Did Tek make their own knobs or outsource ? What about the earlier 'Black & Red' sets for 500 and 560 series scopes? I think there is an interesting story to be told about knob design and layout (ergo

7B70 - Known/Standard Mods?
Is there a MOD sticker on it anywhere ? Maybe not relevant, but there was a MOD to the 7B71 for use with the 7704A DPO. Just wondering whether they both (7B70 / 7B71) needed a MOD for the DPO . Hakan'

Patch cable for 7S12 015-1017-01 (750 pS)

7S12 diagnosis needed

[OT} Peak DCA55 & Germanium
My Peak DCA55 often misidentifies some Germanium transistors as BiColor LEDs. In particular those such as 2N2209 with TO7 bases. (e-b-Case-c; the Case lead has been clipped). Is this possibly Tin-Whis

You never know where Tek stuff will show up
Pre-retirement, I worked for a University in UK. Almost overnight, it seemed, many of the research departments decided to 'go computer', and there was a mass dumping of analog equipment, particularly

Also a quick glimpse of a Tek 5000 rack-mount scope with an orange CRT filter. P7 phosphor option ? (~9:23) I've always been interested in the 'synergy' between Tek & DEC - the automated microprocesso

There is a tiny knob on the front panel by the Timebase B controls. That needs adjusting fpr effect. Tim

Tekwiki mentions the Oregon Analog ASM7 which does exactly that, although I've never seen one, or heard of anyone having one. Wonder what happened to it? (Pics under 7000 3rd party) Tim
