6L6 / EL34 valve bases for double sided soldering?

[N_Cook]

Google images found none. Instead of pins in a ring of <>18mm diameter ,
they are on a <>27mm diameter so that the top side of the pin, lays
outside the porcelain/matrix of the base, so can take soldering on both
sides of the pcb. The socket pins have a joggle to them , to accomplish
this.

UK supplier that is, I can find USA source on Google images with tube
instead of valve search term

If it's worth using valves, isn't it worth using tagboards, wires and
60/40 solder to make a good long-lasting job of it?

Its a followup to posting here a week ago titled

I've had to fudge the 2,5,and 7 pins, stopping htem from twisting, with
0.5mm inserts. I'd have rather found some replacement sockets without
the design flaw but owner wants his amp back.

is a USA source and maybe a different design to the problematic ones
used by Hiwatt .
Need an underneath view to see if the pins are canted, but an
engineering drawing to show if there are the problematic "humps" on the
forks of the pins, would be more definitive

Do you have graphics software? You don't have to be an artist to produce a
simple layout of this sort.

Sorry, I can't be much help. I didn't realise your enquiry related to
an already-existing amplifier, I thought you were making one from
scratch (or, at least, part of one).
