The other culprit could be PIN3B socket as it is a bit delicate, although you have checked the board. Might you have wobbled it when changing caps and loosened its soldering joints underneath? If it is not faint over the headphone output (via the op amp board), then that could also indicate you've cracked one or more solder joints under PIN3B.

The only other thought is static, or if you made the change when the unit was powered up.

Andrew,

I've tried the variable output, the fixed output, and the headphones output. All the same very faint sound on full volume. I've checked all the grey ribbon connections between the two PCB's with a multimeter all show to be ok. Looking under the PCB now around PIN3B, no obvious cracks.

Bit of a mystery, a very expensive mystery, with the the murata regs, elna II's, god knows how many ops amps I've bought in the last 12 months.

I'll keep checking but may have to just bite the bullet and start again.

Hello Stanley any weekend Caiman specials coming up ?
