This weekend I will be finishing the whole Milq modefication, putting it back to the full-time service and this Sunday the James Levine’s live-to-tape broadcast of “Simon Boccanegra” is was planning to listen via the reincarnated Macondo.
Doing the final testing of the Mlquiades and knowing the now it is a well packed amp I was exposing to violent physical stress, I mean really brutal shaking. The MF was shorting. It was not shoring but I had very loud pops from the speaker, and it took it even further then it burned the 100mA fuse on the DH B+.
I shell not say that I 33240 time check everything possible but it was not visible reasons what was shoring. Then I resized that it happen only with 2.5V tube, I did not treat my 4V tube as violent. Then I narrowed down that it happens ONLY with contemporary Chinese and Sovteck tubes. I have very high quality Teflon socket that do not loose contact but what I stress the Chinese and Sovteck tubes in socket then they short. The RCA, Sylvania and Tang-Sold have absolutely no reaction to streets in the same socket.
Sucks! I spent a whole evening to learn it!
