Pete, yes, that's a 707 behind the R66. That one had all of its AF114/115 and 116s removed and replaced with AF125s, same idea and they still have screen leads, but they tend not to fail.
Fitting those was easy, but removing those wretched modules to get at the little buggers wasn't!

I've another 707 which is a very late one with the striped grille only found on the last few dozen sets built. These last of the line models came with AF124/125 in the IF module as Roberts had obviously learnt their lesson with the 11* ones in those pesky larger cans.
I've not long since finished an R900, the switch is a common weakness on these, in fact I've done about a dozen of them and that's the only fault I've ever had to address, they're unburstable otherwise, if a little too modern for my taste in many ways.
Coming up are pictures of that rare, late 707 and my own R900, an early one with a proper, rubber suspended speaker cone, long throw voice coil and odd looks compared to the more conventional, later version that matched other Roberts sets.
Many more photos of my collection can be seen in a book for which I provided pictures; "Vintage Radios" by Tony Thompson, ISBN 978-1-86126-949-2.
Buy a copy if you can find one, lots of tempting things inside that will have even the most iron-willed of enthusiasts watching eBay like the proverbial hawk.
