You're right, Not an OC(P)71 in sight. And as for the price on those
2N3055s....
Not to mention the ECC80s...
Bah. And:

2 x OC71, and 1 OCC45, IIRC
And the 2N3055 was required for almost all ETI projects! I'm assuming all the old gits here know what ETI is.
That infinite-value capacitor seemed quite a bargain at only 4p.
Then I looked more closely and it was only 1NF...
No OA81? I once mended a 1940's Ministry of Supply radio with one of those - whatever rubbish they used for a rectifier for the IF was long since dead. Used to listen to 208 on that one.
They've got bayonet lamp plugs - in brown and white, also BC->2pin adaptors.
Luxemburg IIRC
and lots of geranium trannies & valves. But GZ32 for =A325, WTH?

for me either! ;-)
I had the OC71, but had to get some substitutes like using a modern trimmer in place of the postage stamp device listed etc.
Got a feeling that book specced a OA91... then again it was over 30 years ago!
Sumlock Comptometer back in the 1970's who started an electronic component supply business - looks like it could be the same fellow.
AWEM
2N3055s are pretty useless at any price. OTOH, only two quid for a real 2N3055H is quite a good price. These are the ones made how they used to be 30+ years ago, and they are damn-near hand-made.
There's also a big trade in faked TO3 power transistors. Sometimes you even get two paralleled dice in there. They work fine at first, but any hint of thermal runaway obviously dumps more and more current into just one of them, so they're uselessly fragile.
and the same stock

A magazine?
Some actual issues in the links here, although all I've seen so far are BC148s and ZTX300s:

Who needs an OA81 when you can get the an OA91 for 33 pence?
Direct equivalent IIRC but in a much smaller package and, thus, much more versatile ...
... or is it your eyesight that is the problem these days ...? ;)
No OA91 in 1960 as far as I know.
