Changles Posted November 8, 2010 Share Posted November 8, 2010 So the valve in my TD650 has come to the end of its life. I bought the amp second hand a few months back and the previous owner had put in a Marshall ec883. I don't know much about the different valves out there. Is this a good valve for a TD650? Or is anything better that I should buy? Does it even matter?! Give me a clue! Thanks Changles Quote Link to comment Share on other sites More sharing options...

Thanks Changles[/quote] Valves come in different grades, but essentially any ECC83 or 12AX7 will work but some work better than others. Marshall valves are rebranded Svetlana's if that's any help? Try [url="http://www.watfordvalves.com/"]http://www.watfordvalves.com/[/url] - I had a set of valves off them for an ENGL combo recently and they were happy to advise.

geoffbyrne Posted November 9, 2010 Share Posted November 9, 2010 Read this - just scroll past the big picture of City Hall & the two embarrased men and go to the article about pre-amp valves, or tubes. Myles Rose is one of the most knowledgeable gents out there when it comes to tubes & he's developed his own testing equipment for the proving thereof.

Wilco Posted November 10, 2010 Share Posted November 10, 2010 I've just bought a Gold Lion ecc83 (12AX7) from this company [url="http://www.hotroxuk.com/"]http://www.hotroxuk.com/[/url] & that was an improvement over the Sovtek 12AX7-WA my amp was shipped with. Whilst doing a bit of research, stumbled across this article which you may find useful.
