I am looking for a schematic diagram of the Beomaster Terminal for the
1980's Beomaster 6000 (Terminal is Type 2035).

There are two versions of this remote control, I need the schematics for
the version using a 20-pin IC with a small diode matrix (the other
version uses a 24-pin IC and no diode matrix).

Anyone ?

Martin

martin,

i MAY just have that... i will check this evening and let you know.

unless someone beats me to it!

Martin,

are you sure this is Type 2035?

My Beomaster 6000 (Types 2251-2254) schematic for Beomaster Terminal 2035 is the one with a 24-pin SN 76831.

In the Beomaster 5000 (2321-2325/2329) there's a Beomaster Terminal 2039 with a 20 pin COP-processor and Diodes in the keymatrix. Might this be the one?

greetings,

P.S. I am following your "classic repair" - definitely something I wouldn't dare as I was always afraid of the twohundred-something Volts needed for valves; My electronic life started with OC70's from TVs from scrap in the early 60s - and 4.5V batteries 

Hi,

Yes, it is indeed a Terminal 6000.
I agree that it has a very similar circuit to the Terminal 5000 but not quite
the same... I have a fault in the button matrix and as the contact board is covered
in black plastic, I would prefer to look at a diagram to select
areas to attack rather than take it all apart.

Valve stuff is fascinating and exciting to work with but it does take time
to get it right and you do have to be careful. As you say, voltages as high
as those usually found in valve things should be respected.
I haven't had much time lately to work on the Beolit 39 but
the thread will, hopefully, soon be updated.
Thanks for your interest, greatly appreciated !

Turned out the Terminal 5000 schematics were close enough and a closer
inspection revealed the problem to be with the IC itself so I am now looking
for the 20-pin IC, a board or a whole Terminal 6000 to use for parts for an
otherwise mint one that I would hate to give up on.
Something spilled in/on it, burn marks, worn lettering or similar is no problem as
long as the electronics are OK.

Anyone ?

hi guys...

sorry for the delay getting back to you, and frankly this is a bit confusing to me...

my man clearly states that it is for a type 2035, but shows the same 24 pin sn 76831???

martin, if you need it -i will be happy to scan it for you, but it doesn't sound like what you are looking for...

Thanks, I have the manual and schematics with the 24-pin IC so no need for that.

I believe both versions were type 2035
and they are completely the same on the outside and in function. Actually, the 20-pin version is
the one' I've seen most often.
