    Have you tried isolating the problem by wearing your headphones backward to see if the channel imbalance flips ears (stays with the R channel earpod)? When mine seem imbalanced, turns out a good ear cleaning does wonders.

    Happy Birthday Birgir! 🎂 Hope you have plenty of Brennivín to wash down the Hakarl and Surir Hrutspungar!

    I’ve found unrolling the SR-009 earpads inside out gives more room to work. Makes it easier when removing the inner cloth dust shield and getting at the small screws for disassembly and assembly. When all reassembled, just roll them back over themselves.

  8. Hi John.

    Not to threadcrap on your Yggy For Sale thread, was wondering what you are using for a DAC instead ATM. Just looking what others are currently enjoying. 

    Thx

    EL34, 6CA7 and KT77 all have the same functional pinout, so don’t know why adapters would be needed. EL34s and small bottle 6CA7s are pentodes with suppressor G3 brought out on pin 1. Big bottle 6CA7s and KT77s are beam power tubes. NOS and Russian reissue tubes are tetrodes and have the beam forming plates internally tied to the cathode. JJ 6CA7s and KT77s are beam power pentodes which the beam forming plates are brought out on pin 1 for external connection. Depending on the circuit these JJ tubes may cause problems if the beam forming plates are not connected to cathode potential. Justin at Headamp explicitly says NOT to use the KT77 in his BHSE amps. SO DON’T USE THEM IN HIS AMPS. I’m currently using a quad Gold Lion KT77s in my GG, and liking them a lot. The opto-servo in the GG might be the reason they work here (so far.....). Does not necessarily mean they will work as a EL34 replacement in all cases.
