The Export Marshalls to the US had 6550s right through the JMP era, never heard of 5881s used in Marshalls as a stock valve until Marshall changed to them in the early 90s.

:twisted:

Mine definitely is standard with 5881's. It even has it screen printed on the front just above the 'JMP' . There's also a Marshall sticker on the chassis stating that it must not be re-valved with anything other than 5881's. I must have a really rare and ultra valuable price of Marshall Rock and Roll History- I'll start the bidding............ :D

What year is yours? - the 90s Marshalls had that sticker on the front. Also what model is yours?

My JCM900 has the 5881 sticker on the front.

Its a 1979 model according to the paper sticker on the chassis. The serial number places it as a 1979 also. I bought it secondhand in 1983 when I didn't know an EL34 from a, well, 5881!

So it has one of those stickers that the JCM900s had on the front in the 90's saying '5881 equipped' ??? - pictures?

I must say, I've never heard of a '79 JMP with a sticker on the front saying 5881-equipped. It's even more wierd since EL34s were in plentifull supply, hell - Marshall were still fitting Mullards and Siemens EL34s in '79.

Are you sure it hasn't been converted in the 90s when there was that EL34 drought?

:twisted:

No conversion, as I said I bought it in 1983 when it had original Tung Sols!

I suppose there can always be oddballs. Still, to the best of my knowledge Marshall did not use 6L6s on a regular basis. Someone could easily have put them in the amp, not necesarily the original valves.

Still, some nice valves to have - Tung Sol 6L6s rule.

Ill bet you could custom order any minor changes made to the standard line, would be logical IMO. My '90 bluesbreaker reissue has 6L6's but i dont have a clue if they were in there originally. It does sound somewhere in between marshall and fender which is pretty unique IMO.

The Bluesbreaker RI's always came with Sovtek 5881s from what I can remember - I know mine did, as have all the one's I've worked on since.

You can put 6L6s in them with no problems, they're the same family of valve. I used to run small bottle Philips 6L6WGBs in mine and it was a bang-on 'early ZZ Top' amp.

:twisted:

OOHHHHH now youve done it!

You know im looking for a strat right and that BB sound youre talking about would be perfect for the sound i hope i can get from the strat. I also do like those beards alot, so it would be a double win changing those valves......

Even more to dig into HELP!!!

You're giving me gas too for the early ZZ tone!

pock pock pock ZZ Top tone! cluck cluck cluck

lmao, yep those small bottle 6L6WGBs are great for that raunchy early ZZ vibe and break up really easy.

my fave valves in those amps however are the Chinese (Valve Art) KT66s - they're tighter with more headroom (great for AC/DC).
