Aha! Was Newman street off Charing Cross Road and behind the Odeon on Leicester Square. There were a couple of junky esurplus electronics shops and Chinese restaurants in my day. At the Wardour St end in the 1980s there was a really good,steamy Vietnamese restaurant where the waitress was notoriously bad tempered.
Spot on, Doc.
In my day there were quite a few of those new/used/war surplus electronic places in Newman Street, although it did not compare with Portland Street or Tottenham Court Road. I well remember haggling with a singularly miserable fellow when selling my kit to fund a motorbike tour of the Continent - five countries in 6 weeks with girlfriend on a G3L Matchless. This was in 1962 and for his £20 the miserly git took my TrioTrak turntable (like an early B&O), the big Pamphonic, a Jason (transistor!) tuner and a couple of Axiettes in good cabinets. These were the proper Axiettes - not the spaceship thingies Goodmans produced later.
And ed Have some good and some not-so-good memories of Gower Street. Did my degree there. But London has changed un-recognisably in the 50 years since I lived there. Sadly, DoctorJohnson's maxim applies no more.
I can’t help feeling that moving to Devon in 1963 May have been an unwise move.
The world looks so different after learning science. For example, trees are made of air, primarily. When they are burned, they go back to air, and in their flaming heat is released the flaming heat of the Sun which was bound in to convert air into tree.
Went in a record shop in Leeds today, they were playing some squeaky jazz on a system consisting of a thorens td124 with linn basik lvx and at91, naim nait 2 and spendor bc1s.
It was spectacularly screechy.
Didnt buy anything as nothing was in any sort of order so finding anything would have taken an age
Shame !
If the records aren't sorted it's just a lock-up !
Anyone notice any earthquakes today ?
I think I was either driving or walking around Ruthin when it happened, didn't notice anything.

I usually have a 15 mins shut eye in the afternoon and I was woken by a gentle shaking. I am around 100miles away. It wasn't a dream - 'er indoors felt it too.
Is there anyway I can order a batch of transistors with more likelihood of getting the hFE range I need.
I received BC327 with a useful spread mostly in the high 400s but the BC337s were mostly in the 300s.
They are for a Paradise Phono amp and I need close matching. Might I stand a better chance with a particular manufacturer? These were all Diotec with the NPNs being on ammo tape.

Datasheets both say 100 - 630, so on that basis they're all good. Apart from getting the seller to match them before posting, I don't know. Doubt there's any of them these days knows how even.
"No matter how fast light travels it finds that the darkness has always got there first, and is waiting for it."
They know how, but you might wilt at the price for the service. Most designs if they need matched pairs or quads will use arrays like the THAT300B, but that phono needs needs matched PNP and NPN, however other than the OCD that it seems to bring out in people, I dont know exactly how matched it needs to be and what are the results of not matching. The circuit has 33R emitter resistors so they should prevent current hogging.
