Does anyone out there know the brand and/or part number of the scope tube that was used in the Marantz 2130 Tuner ? Mine's gone sideways (literally) and my tech has no info (brand or otherwise) to try and find a replacement for it. Any info would be appreciated as well as where I could possibly find this holy grail.

Thanking you all in advance........

Axle.

Thanks for the reply !!! I found the Hitachi tube and part number you sent on another forum but can't find one yet. Would you know the brand name for the part number VB00235012 ?

From what I remember,you will have to search Europe, specifically Germany.I don't believe anyone in North America has them.Try Ebay in various countries.

I had a 2130 with a scope that appeared broken; it displayed a large jagged line regardless if music was playing or not. Turned out some small capacitors on the scope board had failed. The repair cost a few dollars in parts, plus about an hour of labour. I suggest you ask your tech to look into that possibility, or find another tech who will. It's extremely uncommon for the scope tube itself to have issues.

First: I would follow "Retro Audio" advice, and if no joy...

Second: Put your question to AK, http://audiokarma.org/forums/index.php? ... r&o=date&c[node]=134
They have more Marantz owners in that Forum, they might have an answer for you...

Sounds like your tech has no clue. The fact that your scope shows some display means the scope tube is fine! Look for another tech.
