Question on tube rolling with Melody I2A3....

Hi

...a little late but I just bumped into your post when searching for other info

I have a similar system as you, Melody 2A3 mono block amps and Reference 3A MM de Cappo-i speakers and so far I've tried these 2A3s tubes;

stock Sovteks - in the melody
Super TNT - in the melody
JJ/Tesla 2A3s - in the melody http://www.6moons.com/audioreviews/jj2a3/40.html

The JJs tend to be clean. I like them better than both the Sovtek and Super TNT.

I'v also tried some different 2A3s in another amp (only needed 2 tubes)
2A3 Aria -- http://www.enjoythemusic.com/tubelust/aria.jpg

ken rad - in the Aria

Sophia Electric Princess - 2.5V/300B mesh plate tubes (2A3). - in the Aria

I don't know why the ken rads are so expensive. Maybe the ones that came with my amp were near end of life but in any case to me they just suck. The KR is also a mono plate where most 2A3's are a dual paralleled plate

I've also tried a pair of Sophia Electric Princess 2A3 tubes in my Aria 2A3 amp. These are even more 3 dimensional than the JJ/Teslas.
They have more punch and slightly higher power than the Sovteks and are more linear and are also smooth in the upper end. If I ever get another deal like the last one, then I'll pick up another pair and give them a whirl

Yes, do be sure to give the Sylvania GTB's a try in this amp. The stock 6SN7's give the amp a warmer, thicker midrange that is relaxing, but the Sylvanias made it faster and more neutral, with lots of detail and attack.
Extension on the highs are now amazing. I also tried some of the more desireable 1940's Sylvania VT-231 6SN7GT's in the amp, which gave me even more detail, but they were a bit too lean in the midrange. The GTB's had better tonal balance.

That's great to know. Thanks a lot for that info. I'll try rolling the driver tubes like you recommend.

I have looked into this as well.., The 101D you mentioned can be found new on E-Bay for $240/pr mfd. by Guiguang, or TJ makes a meshplate version for the same price, available at DIYAudio site.

I have this amp as well and wonder what to do when the time comes to replace the power rectifier tube, the round one. It does not appear to be available and I don't think there's a dealer any longer for the brand. Any ideas? I love the amp.

Pick a Dealer that you can trust first. There are a number on Audiogon.

Simple, Shuguang 2A3C! From Pacific Valve.
