    I would look for a hexfred alternative, just compare specs.

    Th 1N007 is rated for 1000PIV. Might be a problem with fancy diodes.

    You can always use a 1N007 with 10-22ohm (1W 600V rated) resistor in series to simualte a valve rectifier ;)

    Yes I've found that too, not totally sure I'd pay out for them again though, cost me about £30 for 4 with shipping

    I've found schottky diodes to sound far better than standard diodes and even UF's, the hexfreds I've not heard butif they work in the same way as standard diodes I would expect schottky's to be better.

    depends on where you use them, they're not always worth the bother/money and they aren't always the best choice although in a tube amp IME they probably are

    Ive had to be abit budget orientated on this. I couldnt find and schottkys of the value I wanted so Ive got some ultrafast soft recovery variety. A certain hi-fi diy supplier wanted £3 a piece, RS 0.29p for the exact same thing, thats a fair old saving in my book!

    Yes you often find that with 'certain' DIY hifi suppliers.
