A good Valve manufacturer for 410HJS ?

Post by valvereaper » Sun Sep 09, 2018 5:25 pm

Received the amp last week. Great apart from an arcing el34! Not sure if it’s another one setting it off but tried a quad set from another amp. And need a new quad.

So it’s possibly either Marshall quad off eBay £40 or Watford Valves JJ mk2 est £68.

Thinking the Marshall set for the time being. Just not sure what real make they are or how reliable. Especially after it was a branded Marshall valve that was arcing.

Haha, so I was not the only one who had valve problems on new amp. When I bought it was one or two faulty in preamp. Swtiched all, didn't want to bother investigating. Marshall have mixed original setup. In preamp silver/white letters are chinese ones and the ones with red letters are JJ's. I believe that power amp valves are also chinese production but not 100% sure. I am using JJ's in power amp and no problem so far. Didn't noticed any change in sound when switched from those chinese ones to JJ's. But thats me :), I bet other will tell you different.

So I have another valve swap requirement in my HJS. Power amp valves are playing up again !

Can I ask what is best to replace the EL34 with (I won’t get a chance to get up to Marshall for the usual service before Xmas gigs!

Hotrox have some JJ el34 and e34L anybody know the difference or suggest another appropriate tube?

Hoping I can also get away without rebiasing...

Whenever you put new power tubes you need to check bias.

Valves are on the way but rehearsing tonight so hope it lasts. Noise as similar to in this vid https://youtu.be/dHSYBvuTNRE but never get quite as loud. Hope power valve swap is the right move!

You ALWAYS need to bias new tubes.
