    Hey all,

    Looking to get my ENGL Fireball re-valved. Can anyone recommend a good repair guy to look after this in Dublin?

    Not into doing it myself, thanks.

    There are some numbers in the sticky at the top, but I recently heard that Alladin's doesn't do basic repair/service anymore (focusing on vintage refurbs, apparently) and that Martin Nolan is restricted in what amps he can work on by virtue of being an official Marshall tech (eg won't do Blackstar).

    Anyone know if this is true?

    Are you going to change all tubes or power section only ?

    I don't think the Marshall thing's true, the last time I was down getting a cab repaired he had a Blackstar Series One on the bench and a couple of Fender amps around it.

    Jimi's in Ballymount is another option, or Owen up at Someneckguitars.

    you should *always* change the driver when you change the OP valves (unless you have something awesome & expensive in there like a Mullard Blackplate or a TechTube, and it's not gone)

    If there's a valve rectifier you should change that too - tho lately I've gone over to rectifier simulators instead of valve recs.

    Why ?
    Driver stage is a separated part of tube amplifier and could be changed independently from other factors

    Because the hardest working parts of a valve amp are (in order of stress during operation):
    1) the rectifier valve (doesn't apply to amps w/ silicon rectifiers;
    2) the output valves;
    3) the driver/phase inverter valve;
    4) the preamp valves;
    5) reverb driver/tremolo circuit valves (assuming the rev/trem is not on all the time).

    So, unless you have one of those indestructible valves of yore (like the aforementioned Mullards) then you should replace the driver w/ the OPs.

    The entire signal of the amp is channeled/summed through that one valve before distribution to the OP valves. If it's weak - your amp will never perform properly.
