Hello I am in the process of putting a Drake L 7 amplifier back into operation. I was advised on this forum to bring the anodes of the 3-500Z to red to maintain the quality of the vacuum.

In the same way that there are synthetic white noise generators, from a pseudo-random code, are there synthetic pink noise generators? This pink noise modulating in SSB seems to me to be a very

Excellent idea...... and I had forgotten all? about it.? ?My Behringer DEQ-2496? ( 24 bit - 96 khz)? mastering processor has a pink noise generator in it.? ?I checked my old notes, and when fed
