steer clear of the A/B/C models unless:

1. you know where it came from and the service history behind it

2. it's absolutely spotless and the CRT shows no signs of fade or burn

3. it's so damn cheap you can't resist it (like <$200)


these monitors pack a lot of features in one box (even the old A model) but service is a big question mark. depot and parts support not longer exist. most people buy several of these just to use them as hangar queens to supply parts for the working unit.

any questions you have i'm sure batlabber bernie will be able to help you out... PM him if you want... he's money in the bank on these monitors.

My two bits worth:
The factory no longer supports the A version, many components are no longer manufactured.
The A came out about '79.
Both the high voltage supply (A-10), and low voltage (A-1)
are very difficult to repair.
the B came out in the early 80's, functionally identical to the A, with updated power supplies, as well as final revision boards.
The C is a B with 3 new cards (A-3, 7,9,2 jumpers).

I use an A on my bench at Pacific Wireless (Formerly, Motorola area KW)
I have been repairing these since they came out.
There are many parts that are hard to replace, or expensive.
The CRT is still available for $1300.
On the other hand, if you can get it cheap, and the picture is good, and it appears to still work, it might be worth while to the occasional user.
A comitent electronics tech should be able to repair most problems.

I have a D model, and I like it better than my 2600.
Its the best service monitor I have used.
(Just my opinion)

My two bits worth:
I have been using the R2001 since 1980.
I also own a R2009D/HS, R2600B.
I agree that the D is the easiest to use, the controls are very intuitive.
It is possible for some one that has never used one of these to use it with out consulting the user's manual.
It is reliable, and stable.
The case is rather flimsey, easily damaged.
The RF synthesizer is much easier to service than the earlier A-5.
The duplex generator is also easier to service, as are most modules.
Un fortunately the Test equipment department no longer exchanges modules, however they will still repair R2001D.

It is necessary to find substitute replacement parts for those no longer available from Motorola.
I have found a replacement time base much better than the original.
Isotemp OXO143-2, which requires minor modifications.

The Motorola R2600B is very accurate, but not very easy to use.
It's outstanding merit is it is light, easier to carry up stairs.
Not to mention the tracking generator.
Must be returned to Elgin for repairs.
Aloha, Bernie
