Nope... 0.0937uF rounded up is 0.1uF which is 100N.Mooger5 wrote: 0.0937 isn´t 10n instead of 100 btw??
AG has mentioned the two field coil speakers in passing - unfortunately they need reconing.
I am probably going to retain the 3 oil filled caps in the Novachord - it's the wax/paper caps in the PSU that must be replaced, along with the resistors as many have overheated and some are many tens of percent out in value!
I take on board your comments about the sonic qualities of oil/wax/paper caps vs modern polyester caps. Talking of retaining original passives, I feel carbon resistors will always be inferior, especially noise and temperature stability wise, vs a metal film resistor. Where I do agree, is that there is a good chance that a modern polyester cap could change the timbre of an analog synth - especially a tube synth where most of the circuits are very high impedence. In such cases, more than just the basic parameters of a cap matter. Both the ESR and inductance of a cap could play a part in the timbre too. Where this is very likely to make a difference is in setting the Q of the LC resonators. I would be very interested to know how Phil Cirocco's filter network sounds compared to mine. I would also like to know what his oscillator and divider waveforms look like.
I wish to leave as many original parts as I can in the main generator chassis but I'm not in the PSU purely for safety reasons. If the PSU does not run to spec there really is no chance of the Novachord being safe, stable or noise free (ish). The PSU in the Novachord is abnormally complex for a tube design and plays an active part in noise suppression (mainly noise generated by mains ripple and the divide down architecture itself) - it's therefore very important that it works correctly.
