Thanks Phil.

The 800va ones look like a good deal on Phil's list. Can't believe that I got mine from Polar this time last year for £88!
Just be very precise with the measurements, Nick. Fitting the toroid into the space between the power amp PCB and the amp sides is a bit tricky, it takes a bit of rotating around the M8 bolt to get it right.
PM me if you want me to take the top cover of my 400rb and check anything, Nick.

[size=4]Hi Martin, Measured about 42v on the secondary's. Regarding the price, you did well to buy one when you did. Apparently, [i]'[font=Verdana, sans-serif]the actual manufacturing cost had increased over the last decade but had not been updated incrementally over that time by GK'[/font][/i][/size]

Be very wary of getting it from polar audio. I did last year for a 2000RB. They sent one with the wrong electrical values and it blew the amp main board.
GK were very helpful and basically supplied all the internal electronics required to fix it "free of charge"
Check the spec of any transformer with GK before you fit it.

Thanks for the heads up Gelfin.
Not sure what to make of Polar Audio TBH. When I first enquired, they quoted £65 (exc VAT). Then I received an invoice for £186. However none in stock, lead time of 8+ weeks.....
After replying querying the price, I received an email from Polar admitting 'a price disparity' which was to be investigated with GK....
[size=4]Polar Audio have now got back to me to inform me that the price is actually '[font=Verdana, sans-serif]correct as [/font][font=Verdana, sans-serif]it was recently determined that the actual manufacturing cost had increased over the last decade but had not been updated incrementally over that time by GK'. [/font][/size]
[size=4][font=Verdana, sans-serif]To be fair they are now offering the transformer at reduced price of £133 and there is now one in stock(?!)... [/font][/size]
[size=4][font=Verdana, sans-serif]This has gone on over past fortnight, phone calls & emails.... I'm not even confident now that I'm going to get the correct transformer. [/font][/size][size=4][font=Verdana, sans-serif]So I think I'm gonna look elsewhere.[/font][/size]
[size=4][font=Verdana, sans-serif]Gallien Krueger make great amps, but this is not good aftersales or product support IMHO, not from from this experience.[/font][/size]
