Am i just being blind or is it very difficult if not impossible to buy 2M 1/4 watt 1% metal film resisitors in the UK. Loads of places do 2M2 ones but nowhere will sell me 2M ones apart from some place in Hong Kong.
Anyone got any ideas?
2M2 should be close enough. If you really *really* need 2M then use two 1M resistors in series.
Don't be too fussy about 1/4W, either. If you can only find them in 1/8W that may well be perfectly adequate - to drop 1/4W across 2M you'd need to be dropping about 700V.
i was considering the two 1M method but this is actually for a proper PCB which needs about twenty 2M resistors so it's going to get a bit messy with 40 1M resistors poking up all over the place.
I can't find 1/8 watt or 1/2 watt 2M ones either.
I might have to go with 2.2M if i can't find 2M i guess but i'd prefer not to given the choice.
I could always just buy these http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260435344219 but it annoyings me having to wait ages to get somthing as simple as resisitors al the way from Hong Kong.
maybe this?

What exactly is the circuit? Is 2M 1% a hard requirement, or can you play with it a bit?
Its the analogue board from the MFOS 16 step analogue sequencer. The sixteen 2M resistors go out to the tuning pots on the front panel so i'd imagine i could use 2.2M one if i just tuned everything slightly off but its not the best solution, although i'm not entirely sure how the tuning knobs position relates to real life anyway.

All that'll happen is that you'll have a tiny bit less swing on your fine-tune pots. Don't sweat it.
for some reason i was reading it as being for the coarse tuning pots but looking at the component layout it does seem to be for the fine tuning ones which i guess isn't as much of an issue. ;)
Y'know you could stack several of the gate boards and have slide and accent outputs as well. Have a look at the 303 circuit diagram to see how the slide part might work.
