Tektronix AM503 current amplifier

[Jim Yanik]

I just got a email from a UK gent who downloaded a lengthy 2213
manual(pdf) and it didn't even have the power supply schematic,one of
the MOST necessary diagrams. Unfortunately,I do not have a scanner to
digitize mine.

Anybody have a readable digital 2213/15 PS schematic or link to one?

To add or clarify,the UK gent DL'ed from the bama site.

Why is it Europeons throw straw in the air when it's they who are
LOSERS ?

Why is it the US cowboys fly off the handle when it's they who are the
great winners?

ACK Jim, this is an error in the 2213 manual on the bama & it's mirror
site: service manual is complete except the schematic of the power
supply - which is missing.

I've no schemetic or link handy now, but I do the search and if
successful, I 'll post here again.

Wasn't that power supply outsourced, and considered a module level
repair?

No. The original triac-based pre-regulator was replaced by option 48,a
TL494 based switching regulator,on assembly A18;an added PCB.
(I've got one in my 2213) It eventually became a mandatory mod.
(those who failed to send their scopes in to TEK for cal or service missed
out and will never get one now)

The triac pre-regulator had that noisy big inductor on the rear chassis.

The rest of the 2213/15 power supply is on the A10 main PCB.
(power inverter/oscillator,HV and Z-axis circuits.)

I wasn't sure. That's why I asked. Thanks.
