Genuine K20-WAT's seem to be in short supply here in the UK, or at least expensive at near twice the price paid a while ago, K10's seem to be about £7 which is the same as they used to be.
Now, tedious I know but what's the difference between the pump diaphragms? The K20 being the beige almost woven looking one and the K10 being the blue cellophane one.
I ask because the last two K10's I've bought have both the long and short needles but still the blue diag, used to be only a long needle and I used them in old 024's and had to buy K20's for 026's.
Seems odd to add the short needle unless they're phasing the K20 out hence the availability and price, other than the pump material I can use the K10 for my 026's. Just wondering if anyone knew why they use different diaphragm materials? Ethanol? Pumped volume?
Cheers.
