as i have become an OTL junkie, there is a nice thread at diyaudio
about Tim Mellows OTL....http://www.diyaudio.com/forums/tubes-valves/204960-new-tim-mellows-otl-project-14.html#post4957956

just the other day, i wanted to do a 6336 pp power amp,
then i had a thought, an OTL will just need a power traffo and
no OPT's.....so quess what? i am making one.....;)

Ayus Sir Tony, parang burn in narin ba ito, does it consume as much elctricity as when its playing with source?

6L6GC pp amp done....
i designed this amp to use a 12ax7 voltage amp and 6SN7 long tail phase splitters, but i ended up with the 5814 voltage amp and 6SL7 long tail phase splitters instead....
 i found the latter combo gave me the intended results i was after...

6336 OTL.....in the making.....
wired up the heaters for all tubes and power draw comes down to 160 watts. so that 80 watt power budget for the 4 output tubes add up to 240 watts....that is a 100 watt lower than in the 6C33 case....

Sir Tony I'm very happy with this line amp, beautiful SQ, transparent open sounding & really fast. I preferred using the balance connection. As expected napuyat sa pakikinig hehe  ;D

Thank you very much sir!

Hi Sir Tony, I am currently scouting for a tube pre-amp to match my current tube-amp. Design wise will you recommend the PAS2 over a PAS3?
I have not yet heard these 2 models mentioned and solely banking on reviews and recommendations. Thanks.

my comments are not really worth much as that is only true for the particular unit, other units may have other issues from this one..
so the best thing to do is to examine carefully any unit you may want to buy before paying for it...

Sir Tony,
question lang sa mga dynaco kits especially the ST-35. how the sonic of this amp? and the build difficulty? is it worth it to build or hanap na lang ng ibang design that utilises the same el84 tube?
