Ok, I've not posted in this thread for a while, but today I picked up my first 400RB MK4. It's in good nick, working fine, and sounds very nice. It doesn't sound exactly the same as the earlier MK1 and MK2, but it has it's own thing going on and I do like it. The settings on the amps in the pic are the ones which most make the amps sound like each other. Notice the lower setting on the Boost pot, as the MK4 seems to have lot more boost on tap, and also slightly more Treble and High Mid is required to make it sound like a MK2. The Mk4 also has a more pronounced bottom end, like it's extended in the lower frequency range vs the MK1 and MK2. I do perhaps regret selling my MK3 to @Minininjarob, because if I hadn't I would now have the full set!

Looks great! And you’re never getting your Mk3 one back, sorry, I love it too much!! On the plus side a few people have tried my amp out at gigs and they love it, so at least it’s being used to spread the GK joy around. I use mine with a modern GK CX210 and it sounds glorious. 
I used to wonder why you owned so many but I am constantly on the hunt for another GK, but I’d actually want a 700rb just to have a bit more power available - not been short of it to be honest but I’d like to try one and it’s always good to have spares!!

I just got another 700rb power amp module for £30 and a preamp for £15.

Repairers can't seem to be bothered with fixing them so it's a good backup. 

 

I've used my old 700rb for 10 years so they work for me, small enough and more than loud enough so if I can keep it working myself, all good. 

 

Thanks for the heads up

I think I could fix one if I got the chance, I do have a background in electronics and I’d love to have a go and bringing one back from the dead so let me know if you ever find one.
