Hi all,
I've just been "tipped" by a good friend the 7A29 has a very delicate input switch - mechanically, the rollers need some lubrication to perform well and last. I appreciate the heads up, as the switch feels fragile and particularly sticky, so I'm sure I was heading head first into permanent damage.?
I searched the archives (not very deeply, yet) but I didn't find good direction on this yet.
Has anyone done this work and have some good recommendations? What lube to use, where to lube, what not to do, some steps maybe, etc.?
Thank you,
Radu.?

Hi all,
I have a 7k plugin I thought I successfully repaired the pulling mechanism (the finger pull knob broke from the plastic insert that is attached to the spring, and I epoxy glued it together, but if failed quite quickly). I removed the two plugins to the left and right of this stuck one, but I don't see to be able to pull it out if I grab it by the sides.?
Can anyone share any experience on this, please?
Thank you,
Radu.?

Radu,

the power light bulb DS308 at the front is a cartridge lamp, 5V 60mA, green (Tek 150-0121-02), that can't be opened normally. The 2 cables are glued on, or potted completely. (Never tried to open something.) It seems, there are / have been some manufacturers, that produce it.

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!

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.

Paul,
The amount of labor and possible spare parts to bring back a 2430 may just not be worth it, I'm sorry to say.
I would opt for a high serial number 2430A (B030xxx, even seen B042xxx) and in good shape.
These go really cheap on ebay (I've seen less than $100), especially if not working and the high s/n ones it is usually the power supply.
The high S/N 2430A's will have the latest version of CCD (-05) and you will avoid many issues with the older CCDs.
In my experience 2430A with CCD before? -03 will be problematic, so forget the 2430.

It might be appropriate if *ONE* of us contacts Linda to
find out if she is just clearing up Dave's obligations, or,
if she wishes to keep the business running as a source of
income.

I would hate to dump a load of orders into her lap, if she
is just trying to clear up Dave's open orders... But, on the
other hand, I would hate it even more if we all stayed away,
when she was hoping to use the business as a continuing source
of income.

I would do it myself, but I barely have a relationship with
the business... Anyone who actually knows Linda might be
better.
