Radu -

The 7104 is a very interesting scope (I have something like 3 of them). Does your's work - if so, are there any burns on the CRT. You need to be particularly careful of intensity - there is a warning LED that tells you to turn the brightness doen.


It is relatively easy to "split" the unit by lifting the front of the top half up and leaving the rear hinged - completely splitting the two halves is harder. It requires disconnecting multiple cables and is in my mind a "bitch."

Getting to anything mounted on the top of the bottom half is something less than fun. Remove the trim covering the top and bottom half separation, then there will be some screws (as I remember) and you can lift the front of the top part. There is a "kick stand" to support the top part.

Do you have a manual copy? A second question - did you ever get the 7903A to CA from the east coast?

Cheers!

Quoting Radu Bogdan Dicher <vondicher@...>:

Hi all,
It's been a while. I hope everyone's doing just great!
I lucked into a 7104 for the princely sum of $20 ($40 added a couple
of 7A19s and a 7B92A came "free," all basically functional as I've
seen home). Go swap meets!!
Still exploring it and assessing functionality, but so far so good.
One thing I'll need to look into is the power light bulb. I think the
part number is DS308, and may be a 5V bulb. I can't really confirm
this from the SM - has anyone looked at this recently, and can
confirm?
I think replacing it involves separating the display unit from the
base (involving some "kickstand?...") - if anyone can shed any light
on the process I'd appreciate it.
Thank you,
Radu.
