Just putting together a shopping list and the BOM for the LFO v1/2 does not specify what type of caps C6a & C6b are. From the pictures and schematic it looks like C6a is a 1uf polybox and C6b is a 10uf / 35v tantalum, is this correct?

On the ADSR they are both tantalum which made we wonder if they should both be tantalum on the LFO too.

Thanks

The important thing is that they should be low leakage types.
So use polyester for C6a (1uF) and tantalum for C6b (10uF) as you originally thought.
If you used a tantalum for C6a it would have slightly worse performance over the polyester type.

Hi Andy,
Thanks for the reply. All makes sense!

Slowly getting my head around the difference in types of electrical components. Capacitors are still some what of a enigma to me at the moment.
