BOZ questions

[Eike]

BOZ construction questions-

I want to increase the ps storage capacitance. Should only C1 be increased?

Fast/soft recovery rectifier diodes with 100VA transformer-
suggest rating specs.

Trim pot C*02 - what fits the available board?

Thoughts on adding LED power indicator - bad for sonics?

Thanks much!

I would increase all the electrolytic filter caps,
but the most useful would be C101.

Diode specs: 1+ amps, 100 volts.

Trimpot - Bourns 3386P package in Digikey
catalog.

what fits the available board?

Is this board one that you etched from the BOZ project page picture, or is someone selling these?

Thanks,
Greg

I think Old Colony is selling them.

BoZ for DAC output?

A friend of mine wants to replace a tube output stage for DAC TDA1541 with solid state one.
We've been thinking about something like BoZ.
My simulations show gain of 18 dB. Is it possible the BoZ to be rearanged for gain circa 30dB?
Thanks

It gets a little tough at 30 dB. I suggest you
think about the balanced line stage BSOZ
and lower the resistance between the Source
pins of the devices until you get the gain you
want.
