Those infernal Klon components...

Hi,

does anyone know where I can get 422k and 390k resistors? these are for the APIs boards ... hoping to squeeze it into a 1590a

I assume 392k?

I've never managed to get these in 1/8w sizes.  Always used a 430k and 390k, close enough, and measuring a few to get the closest.

PM me your address and I'll send you some.

RS 754-5749 for the 422k

390k pretty widely available - but from RS (e.g.) 149-157 (but you could probably get physically smaller ones)

Have you got the capacitors yet? I found them to be pigs to find in the correct values. In the end I bought a Zentaurus kit from uk-electronics as it had all the "correct" value components.

Thanks @marauder - I've just put in an order at mouser uk :S for a 390k figuring it was inside the 10% tolerance.

@Misterg - not sure how I feel using a German site again after a looooooooooooooooooong wait for Banzai

The 422k from RS is 1/4w, the Apis needs 1/8w, unless you put them in vertically which looks a but untidy.

Panasonic ECQ caps for all values 10nf and above,  available from Farnell,  CPC do some of the values, and sometimes cheaper with free delivery on any size order.  Ideally you need the 5-7mm high caps, rated 16V and above for the electrolytics to fit in a 1590A

Ahh - wiser now.

(@ frankus, IIRC, the uk-electronics.de delivery was pretty quick)

Okay, I'll bear that in mind

I put all the resistors vertically in the first APIs I made I am untidy
