[QUOTE="Murray, post: 1027709, member: 3345"] I have some coming in the LM4562 op-amps have been replaced with the tl072. Not as high spec, but they were out of stock at the assemblers, these are cheaper, and pin compatible and according to the https://sound-au.com/project09.htm good in this application. the 072 does have some oddities at power up, I will have a look at the results as they come in. We can always replace them with some alternatively sourced 4562 or even 5532 op amps. Ive done my sums and promise not to run at a loss at R280. :) Murray. [/QUOTE]
