January Sale on Semiconductors
I stumbled across these chaps when looking for transistors today.
They have a "January Sale" on and a large downloadable stocklist of semiconductors which they are trying to clear out at 60% off if you clear a complete stock line. Includes OC71s and lots of manufacturers' own ICs. They may be worthwhile looking at if you have particular needs. Mine are too small to meet their £15 minimum order, unfortunately. ...and no, I have no connection and only just found them...

Re: January Sale on Semiconductors
Hi Jeremy.
I've used them a couple of times before for telly related semiconductors and other more run-of-the-mill stuff so as to meet the minimum order requirements. Very speedy and a massive range too but pricey with it. Just adding my twopenneth...

Re: January Sale on Semiconductors
They also seem to stock large quantities of valves, all POA. I've sent a price enquiry for a rare type, waiting to see how they respond...

Re: January Sale on Semiconductors
They seem to be VERY expensive. These companies seem to be popping up selling hard to obtain (?) components, I wanted some LM318's the other week. Some companies were claiming that these were rare old IC's, and charging up to £14 each for them. Rapid electronics still stock them for 68p.
Shop around, look through E-bay or ask for rare components here. Daniel. |

Re: January Sale on Semiconductors
I think the bargains are to be had if you clear a whole "line". If I had a larger order to make up I would for instance include buying all the BF450s (interesting AF11x substitute) at only £2 for all 37 left, although I am sure helpful forum members can supply as well. But as I said, I don't have a suitable need to make a reasonable sized order.

Re: January Sale on Semiconductors
Yes, curious, I had seen mention of a minimum order. If the surcharge is zero, it's just expensive postage then...

Re: January Sale on Semiconductors
I asked for a price for an EBL31, and they replied today - £35.02, delivered in 3-5 days. Compared with some of the time-consuming mods and workarounds I've seen described on this Forum to replace this rare valve in a vintage set, this could be a reasonable price to pay for a new valve when you consider the value of your own time!

Re: January Sale on Semiconductors
A certain popular website has someone offering 4 (EBL31) of these stated as "New Tested" at £25 delivered.
I was not aware these were rare and so pricey. I've just looked at a philips 206A today and to my horror the top cap came away!!! Luckily the wire is still intact and can be soldered back. I was entertaing the idea of buying a new one but maybe at those prices not!!! |

Re: January Sale on Semiconductors
Mark5 are one of those companies that I suppose make their money from industrial users of semis, where the prices are more acceptable. Other companies that work like Mark5 are A-Tech, Rochester and Pinewood Electronics.
I've had a few parts from an obsolete specialist that turned out to be counterfeit...its big business in China now. In one case the part blew up at turn on and in another I discovered just before I installed it that the pinout was wrong despite it being the correct part number! Popular fake parts are large audio transistors such as the motorola MJ15024 which can be faked by scrubbing off the label of a cheap 2n3055 and overprinting it with the new number. When it fails after an hour, you're left wondering what went wrong! Many obsolete parts stockists seem to obtain their bits from China and I guess the quality control trail isnt the same as with franchised distributors. But maybe OT and this deserves a thread of its own!

Having looked at some other items from this supplier, they seem to mostly be at the higher end. Probably charging what the market can stand I guess. As to the value of our own time, if we costed put the time we spend on restorations, we'd be working for the proverbial "bowl of rice a day", but I guess that's what defines a hobby. Maybe that's why - to me, and I guess many others, the appeal of a vintage set is inversely proportional to the work already done on it. The more that's already been done, the less I'm likely to show any interest in it. If it's untouched, complete, and in needs of lots of TLC, my eyes light up, so long as the price is right. If I see a shiny bakelite cabinet, I walk on by. I consider that my hobby isn't so much collection, as restoration and conservation. David, G4EBT |

Re: January Sale on Semiconductors
I did a few days contract work a year or so ago for a company that I had previously been employed by, to sort out problems on a batch of boards they'd had made, which I had worked on previously but nobody remaining there knew much about.
It turned out that they had been caught out by counterfeit ICs from a company that has since gone bust. I have no idea what they were under the shiny new print (suspiciously shiny for parts that were allegedly 15 years old) but they weren't Burr Brown analogue multiplexors and they got rather warm when trying to be powered as such! With a bit of research I found that Maxim still made an equivalent IC which was considerably cheaper. I ordered a couple of free samples (Maxim are good with samples) which worked fine. It's worth checking the guarantee offered with obsolete components, especially if paying a significant amount of money for them. The supplier probably won't have tested them so may not know themselves that they are not what they claim to be. |

Re: January Sale on Semiconductors
My boss had some obsolete IC's from China which didn't work.
His dentist X-rayed one and found it to be completely lacking any innards! |

Re: January Sale on Semiconductors
There have been recent cases of Chinese-copy RCDs (circuit breakers for electrical distribution boards) with nothing inside them but an on-off switch mechanism.

Re: January Sale on Semiconductors
The 2sc1969 is being highly counterfeited by the Chinese too. Despite several companies claiming that they're the genuine Mitsubishi component, they're certainly not. 90% of them wont even oscillate.
