Hi All,

Could anyone tell me where I could find a "blank" vertical plug-in module
for a Tek 555 series scope?

Apparently there was a kit available at one time.

Regards,

Andrew

I would be surprised if a kit is still around. When I wanted to build
a custom plugin I butchered an old type 80. The dimensions are the
same and the plug just has to be reversed. I'm sure there are plenty
of junker plugins around at hamfests etc.

Finding a non-blank plug-in for a 555 is tough enough, let alone a blank one. I've never seen one Andrew but I'll keep my eyes open during flea market hunts. Stan G. and Deane Kidd are the only other potential sources I can think of at the moment.

The 555 will take quite a wide range of vertical plugins including the
53/54 series, the letter series and the 1- series. With some of them
(such as the 1A4) you have to be careful that the timebase plugins
have been appropriately modified to remove DC bias from one of the
pins which could otherwise damage the plugin (I have details if anyone
needs them).

Timebase plugins however are not so easy to find - in fact if anyone
has a spare 21A/22A combo for disposal I would be happy to give them a
good home here in Melbourne Australia :-)

Sorry Morris. It was the 21A/22A timebase plug-ins I was referring to in my comment, rather than the vertical plug-ins.

I *might* be coming into some of these shortly. If I do I'll let you know.
