MC275 VI Stock Tubes Opinions

[mati1979]

new stock tubes mc (Ecc83-S JJ) is really very good.
not chinese.

Tung Sol is another very good tube. (to my ears, i like mid-freq tung sol and i like high-freq GLion)
*but i could live with JJ (not chinese old stock mc)

Get a matched quad from Uncle Kevin of Upscale Audio. Problem solved!

If they don't say Made in China on the tube you can probably safely assume they are Russian made.

JJ preamp tubes are made in the reorganized Tesla factory in the Slovak Republic. If they say made in Russia, they are made by New Sensor Corporation at their Xpo-Pul factory. This includes Genalex, Mullard, Electro-Harmonix, Tung-Sol, Svetlana, Sovtek.

AlienViolet.......You are correct, sir. Thanks for the clarification on locations of the factories.

I agree that the input tubes can make a substantial difference to the MC275, but with my Mk 6 I've found the Psvane 88s to add quite a bit of "drive" over my Gold Lions. These are pretty small differences, though, and it can get pricey to swap quads in and out. Had I known I might have stuck with the (in my case, very good-sounding) stock Russians!

best,

I have had my MC275 VI for around 15 months now and am considering new tubes.

I have searched and cannot find a diagram which shows the function of each tube for the MC275 VI. Does anyone know where I can find this?

Also, I see an online company named "Reverb LP" sells sets of tubes for this amp. I was wondering if anyone had experience buying tubes with them?

I love the MC275 VI but am always interested in improving the sound if possible!
