Re: What components do you keep in stock for repairs etc.
Like many others, I've accumulated lots of components over the years and I tend to keep common items like capacitors and resistors in reasonable order. I have about 300 valves as well that I've recently sorted...I really need to decide what I need to keep and what to offer to others.....

Though I'm finding it harder and harder to source trustworthy RF-components [BLY- and early MRF-series power-transistors for example, and proper power-rated Ferrite cores] these days. Traceability-to-source seems to have become fragile - forgeries and 'second-sources-of-unknown-provenance' abound. Who'd have imagined anyone would ever have felt the need to forge humble BFY51 transistors? |

Re: What components do you keep in stock for repairs etc.
RF power transistors are dead and gone now I find hence why I've moved to using switching FETs in anything I design. Cheap and less likely to be forged. I've got 50W out of a couple of IRF510's running at 28V.
RS sell Fair-rite cores so no problems there. And they're a lot cheaper than the usual sources for Amidion labelled parts. FT37-43 .. .25 for £3 approx on RS. Rapid sell BFY51 new from CDIL for 47p a pop min quantity 5. The CDIL parts are all pretty good I find. |

The more space you have, the more you accumulate: Nature abhors a vacuum. The key to collecting / hoarding loads of stuff is knowing where to find it when you want it. And that requires organization of storage: Raaco, cardboard and plastic boxes, biscuit tins - all manner of containers. And shelves and racking, of course. All my containers are clearly labelled as to their contents. For mains transformers, (total over 100) each one has its own catalogue number. They are listed on an Excel spreadsheet with essential data for each. That enables me to find what I want quickly. Ditto with valves, grouped together in boxes according to type: again, a spreadsheet. Of course, such a system requires self-discipline and management - but in the long term, it saves a great deal of time and frustration. Al. |
