Do we know who made the transformers originally? I maintain some old
industrial hardware designs that used pulse transformers from the
mid-60's and I may still have catalogs and/or data sheets.
The DEC part number for these part

Hi guys,
I recently impulse-bought a paper tape reader from eBay, a Remex

It has several enormous capacitors in it and I want to do my due diligence
before powering it up. Does a
Did IBM publish a Program Logic Manual (PLM) for APL\360, APL.SV, or any
other APL language implementation, as they did for e.g. their FORTRAN(E)
and PL/I(F) compilers?
Thanks for the tips, I think I'll replace the caps first as I don't own a
variac. I'd rather not damage anything in case the foil in those caps have
shorted upon application of full power.

Hi Noel,
I don't think I need it it but I know someone on the list for about a year
that probably does. Let me know the status.
Can you call sometime this week?
Thanks, Paul
There are what appear to be 1976 date codes on some caps.
If its that old then replace all and any electrolytic capacitors plus
any paper based caps.
If they aint bad now they soon will be.

Get it over and done with.
The ones that have screws, you can take the chance of putting a scope
In equipment that has regulators, increasing the line voltage can have its
own issues.
I have a very fast acting adjustable solid state circuit breaker.
If the running current is under say 100 W, a incandescent lamp in series is
a poor mans current limiter.
