The starting bid for a single JRC4558 opamp is $9.95, and the shipping is $4.95.  :roll:

What total crap! I can get a JRC 4558 for 80 eurocents at a local shop and I'll I gotta do is bike over there! What idiot is gonna pay for this?

Similarly, I can buy top-quality germanium transistors from a guy in Washington state for $2 each, including shipping to the UK. I COULD then take them to a muso's pub in London and sell them for the equivalent of $20 each. But I don't  :twisted:

Heh... I have a circuit board of an old Yamaha organ that I bought many years ago for parts from a bargain bin of a local pars suplier... It has seven of those (JRC4558DV). Some of them have datecode 0620 and some 0635. I actually didn't buy it for those opamps but for the nice slider pots it has. :-) Some things suggest it has never been used. I haven't actually pulled a single part out of it yet.

Maybe I should sell those opamps on ebay... Nah...

If you wanted JRC 4558s you would probably be smart enough to figure out that this is a ripoff. Come on what difference does it make? If the reissue didn't sound like a 4558, it would have gotten a new number!

While i personally doubt it matters which 4558 you use, it by no means follows that if two chips 'sound the same' in the circuit they are intended for, that they will sound the same in an "unusual" application that takes them to places normally unvisited. it often happens, for example if a logic chip is being used as an amplifier or oscillator, that a circuit might only work wiht a particular manufacturer (or even batch!)

And if people are paying $20 for Ge transistors in pubs.. LETS GO

Tried my first one today. Great Chip for the distortion Stupid Box.
 10 is a bit much for me to care to find out , I think the differences would be 'comparative' at best, and that no solid 'improvement' statements could be verified...but I'll never know for sure.
 Just one of those things I won't be having. :cry:

If he says the original sounds a lot better in his SD1 than the current one, why doesn't he just use it?

Sounds like someones been listening to too much mojo talk (if you moved your 1954 carbon comp resistor 3 microns to the left you'll get improved clarity and bass response!!!!!)

What a load of tosh

Jim :shock:
