Having read all sorts of bad things about these older oil filled
capacitors, I decided to replace the one on my 8a. I got what I think is a
replacement - 6 microF, 660VAC, 50/60Hz, "NO PCB's" - but it is physically
about 1/3 the size as the original.
Did the tech for these get that much better?

Thanks for the tip! Alas, I don't know of any data books with circuits like
that - any pointers? (And it's only the leakage current I ne

Hi
Power factor correction?
Hum suppression?
If its the type in a small squarish soldered up can.
Then open can and remove oil and paper.
Replace with modern type
Close up can and re-solder
Put it back where it came from.

Hi Guys
Well the panel is here and I'm analyzing it to see what it
tells us.
So far it looks like I need to add a band of gray matte base to the front
and a band of similar over the light ports on on the back.
Looks like I have a new product. It's called an "Invisipanel"

Dear Rob,
Just an idea Nemonix Engineering (previous employer) does maintenance and
support for PDP, VAX and Alpha. I know that they had new batteries. Not new
in the DEC packaging but newly mad they may be able to do some thing for you.
Contact Wayne Beeson and let him know I sent you.

My to-do list has me doing the rounds of all my machines to check them all for
the batteries. I'd like to replace rather than remove though, but that could get
expensive at about £10-12 pounds per

That doesn't work for me; perhaps it's because all mail from this list

While I look into what is wrong with my H7864, I'd like to use a modern PSU
to power my machine (actually an rtVAX 1000).
I think I would need to deal with the following problems:
1. Finding the right connectors (ideally, I am sure I could rig up
something more temporary).
2. A

Thanks for the suggestion. This is of course entirely for hobbyist purposes, I
will look for alternatives here in the UK, but if that fails I will give it a
go.

Been AFK and out of town for a week and just catching up on all my email
messages.
I'm on a couple of emailing list where the modified subject header is an issue
of contention. Not sure why, but the square bracket header thing sure helps me.
Everyone else just does this by default.
