EL34 in Cary CAD120S bias info needed

Thanks for all responses,
Plato, what was wrong with your 120S ?
I bought mine 50hrs used - Has transformer hum when turn on.
I just roll with KT88 Gold Lion re-issued output tubes, sound much better than stock but not as quiet as stock (has little hum thru tweeters)

I also try Sylvania 6SN7GTs NOS on both input and driver stages but don't hear much difference compare to stock 6SN7
Best

Plato, you say that your 120s is on its way to cary for service .... just curious... is there a problem with the amp or are you having upgrades done?

"Plato, what was wrong with your 120S ?"

Yeah, please, can you comment about it? also, how do you like the Wyred 4 Sound ST-500 versus de 120S? Thanks

Hi all,
I'm listening to my CAD120 with EL34 now.
One big issue: I can only crank up the bias max 90mA
Yes, with EL34, bias pot hit the max yield 90mA
I send email to Cary regarding this issue - will report back when they responses.
I need to break in new tubes at least 50hrs before I can compare to KT88
Thanks
Thuan

I just talk to Cary tech. To use EL34s, I must modify the bias resistors (2).
Argg! I guess someday when I get tired of KT88's sound, I might give it a try. I have instructions (verbally) if anyone wants to try.
Cary tech insists me to try the mod for sweet sounding of EL34
