In Reply to: A fix for the JJ KT77s maybe??? posted by MIchael Samra on July 8, 2006 at 17:37:19:
I made the mistake of using Chinese ceramic/gold "blade" type sockets in a rebuild of my Dyna MKIIIs ("fork" type socket as you say)They sure looked purty... but rolling a max of 3 kinds of opt tubes in and out of the Dynas made them looser than... (insert misogynistic joke here) They soon were ripped out and replaced with NOS "able to be tightened" sockets, but for a time before I replaced those shi**y ceramic blade-type octals I simply tinned the pins of EL34s with hiqual solder. Worked great; one must use a high wattage iron for QUICK heating of the pin and then cool it post haste after tinning for maintaining the integrity of the pin/glass seals.... I found Svetlana Winged C EL34s quite pleasant in the MK IIIs; but I went back to Svetlana 6550Cs. 6L6GCs and Russian KT66s performed much less well than both 6550 and EL34; sort of a "neither fish nor fowl" situation. The 6L6GCs lacked the sonic balance and midrange "correctness" (musicality/inner detail) of the EL34s, and had a strange "hard" sound. These were RCA 6L6GCs. They also lacked the authority and huge soundstaging of the 6550c. The 6550Cs simply have the most authority coupled with 95% of the musicality of EL34.
