    What would you choose?

    It's a 135watter with JBL D120F speakers.

    In my country it's hard to get anything but Sovtek.

    What would you suggest?

    Any tips/tricks to make it sound "warmer" etc. would be pretty useful.

    help a rookie out :eek:

    with hi plate voltage.. funny thing is unless you have a pile of NOS usa tubes.. the 2nd best thing is those sovtek 5881's they take a pile of abuse
    and hi plate voltages.

    the UL amps were made for loud and clean.. esp with JBL's..

    SEDs are fine in those amps and will warm it up somewhat.

    big OT's with a 4/8 transformer (you need to switch leads at jack and feedback point). There is some other opinions that if you loose the negative feedback resistor it warms it up also (was that london power?)

    If you can get your hands on the JJ 6L6's or winged C ( the old svetlana factory ) these would be your best bet,in my opinion.
