A10 / A12
Hi
Finally got round to doing Skunkie mods on my A10 ( now A12 ).
All I need to say is OMG the difference is unbelievable, improved in every aspect especially the BASS !!
Found the 860 ohm to bright so changed that to 680 ohm, might drop down a bit more as still just a tiny bit bright.
Went with TAD rectifier and JJ output tubes, still using as suppled PSvane EL34, must have got a good pair as image is rock solid.
Have JJ E34L and Mundorf caps on order, looking forward to them.
Thank you Steph.
Just for context my system is as follows :-
Oracle Delphi 2, FR 64 ( Black ) Denon 103 ( Le Son modified ) Tisbury Phono, WiiM Pro Plus ( Qobuz connect ), Skunkie A12, PSB Imagine T54 speakers ( fantastic sound and ridiculous VFM ).
I also have WiiM Ultra and Cambridge MXW 70 connected and switch between the 2 systems.
Regards
John
Nice John!
I remember how satisfying it was when I finished my upgrade as well.
Quite a difference!
From own experience, I would recommend trying Shuguang EL34-B:s, lovely full, detailed and yet very sweet bell-like midrange combined with nice top end sissle.
Also alternating with "real" 6CA7:s ( actual beam power tetrodes, not pentodes like EL34 ) , like the ones from JJ, is worth trying, giving significantly tighter and more powerful bottom end as well as a much more open chimey top end than EL34:s. The 6CA7:s all-in-all are somewhat in the KT88 or 6L6 direction sound wise.
The price you pay is a little leaner midrange.
The JJ 6CA7:s have a just fantastic filament glow, worth it in itself, if you ask me.
