Hi there,
I posted a similar question, and got no reply, just an eery hush. I guessed that you need two similar to those needed for a T4b, which might explain the radio-silence. I have replaced two missing from my (fire-damaged- the only thing that got any corrosion was the lead-in wires of the LDR's) La4 with two from a T4b, and it is super smooth. MUCH better than my other one! I am thinking of replacing the audio path op-amps in it with discrete op-amps to really make it sing. There are no markings on them, and they are very small. They appear to be very, v-e--r----y slow on the release. Someone eventually suggested a silonex dual (NSL-39V62?) but I cannot see how to make this work meself, being a something of a simpleton. If you find out anything further, please let me know!
All the best,
