"There I fixed it!" - ok, so there is still a lot of flux on the board, and the bodge wires are a little big, but bugger me it works just like when I bough it... Cheers for the help fellas I'm off to make a protection circuit now ;)

Low impedance.........

Clean off the flux and it will look like it did straight from the factory.

What are you going to use for protection? A pair of  IDC clips and some 50mA sub miniature wire ended fuses to go in them?

It's not what it looks like,  it's how it works.   Nice job.

Hi!  I created a new topic on  ATF20B, regarding a ATF20B main-board (FPGA) failure and  would like to know if you have some schematics or block diagram of that generator.
Thanks and regards,

I came across this old thread recently and a general lack of info on these cheap Chinese function generators. There have been some on eBay UK for £188.77 inc tax and delivery (from a UK address). The price is as low as it gets...

Attached is the English manual for these, if it's of use to anyone considering one.
