GK 1001RB pre-mkII (first version)

[alexlotta]

Hallo Guys.
I have a chance to a deal on a (out of warranty off course) 1001Rb (not MkII) .It will be under 270£ (about 350E at max)

On the american forum ,i found people telling th. the "old" head ,aside of power output,
has significant differences in terms of tone,and new ones were significant better ,expecially in upper registers.

I 've thought to ask Here ,
du to the the fact that ,Probably,
More people In England did try The old head and had the chance to compare.

..Any tip that could Help me?

........
As a side note,
I'm PRETTY undecided between that Gk1001 and a SA450.Very different heads ,but i found a good deal on sa450 too (about 450€ ),
and i like both for different manners.
My main question is not Mb Vs Gk ,just the differencebetween GK version.
If thishas already ben discussed ,
iwould accept gladly aLink (did'nt find any discussion about).

THANKS IN ADVANCE to everyone willing To help

Apart from the difference in output power, I think some of the GK Mk I amps also had a problem with a particular circuit board over-heating and causing problems. I've think this board can be replaced with the Mk II version, and if the amp has been serviced properly this may have already been done. I've had a 700RB-II for two years now, and it's rock solid!

that's interesting.
i can ask about overheating to the seller (who also modded the amp to 700 he told me today).
Can you clear to me better what i should ask in particular?how did cause problem that overheating,or how it was acknowledgable?

Abou tone also i'm curios ,if is the same or not on the 2 versions

Not too sure of all the details myself, but a quick search on the GK Forum I found these links;

Maybe you'll be able to dig a little deeper for more details.

Thank you!great INFOS!
From what you linked appears Pre board are different,though still good.

Also It seems pre board could be upgraded in the previous model,though i don think is so good "as a deal".
great deal on how it is (maybe the guy would lower to 280 /300 € shipped,which is a good price i believe)
