300B replacement

I recently had a Western Electric 300B die on me. If I replaced the one with a new or newer tube, would i hear an imbalance in the two channels?

Other options i am considering are the Sophia mesh plates, Sophia princess mesh or carbon plates, valve art, or Shuguang nickel plates.

Any opinions will be greatly appreciated.

thank you in advance,

Cincy,

Can the A/B test with the SP Carbon/Mesh. The Carbon will win out by a lot as I have/had both. One Mesh blew out and I have one with 400 hrs on it. What to do with it?

You have good ears as I second your opinion on the WE and SP Carbon word for word. You took the keyboard right out of my hands. =8^)

Phil,

I do believe you do not have the Mesh plate but the Globe.

Gary,

Actually (I think) it is the Globe Mesh Plate with ceramic base. Funny I did not notice the shape of the glass but the mesh plate vs Carbon only.

I have something to look forward to: upgrading to the Carbon

Thank you all for your satisfying answers. It looks like I´ll be trying the sp carbon plates. I know I liked the regular Sophia Mesh plates, but it seems that the sp carbon is really a big improvement.

The meshplate tubes are not built to WeCo spec, their maximum plate voltage being below the standard WeCo spec max of 450 volts. A few amps, like the VAC Renaissance amps that feature a Class A circuit and constant high plate voltages (430 volts), cannot use the meshplates.

The claim to fame of the meshplates is delicacy, transparency and finesse, but they have to be used in the right amp.
