PM sent to tripancakes!
Payment sent

Received my chips today - very tightly packaged with electrostatic shielding. Seem to be in good condition.
I'll have more news soon as I'm waiting for a set of parts to use the chips.

Cheers!

Have more updates regarding the two chips, after taking them for a spin.
- One of them is working well, including the filters. Wonderful sound.
- The other is partially working - the filters seem to be dead. For basic usage it works well, but as soon as I turn on the filters the volume goes really low and becomes almost inaudible.

Will try to reach OP to find a solution, but I'm interested in keeping the faulty SID.
 
@ajk: Payment received. Thanks!

@tripancakes: If volume is really low the filter seems to be simply stronger than usual (the filters of 6581 do vary very
much unfortunately). Even when comparing two chips produced in the same batch/date.
Defective filters tend to make the signal completely inaudible.
However I will provide a replacement as already agreed!

Talked with OP and sorted out the situation.
As per forum rules, I'm confirming here interest in two more 6581 R3 chips.

EDIT: Replacement chip arrived this week, it's working 100%.
