Hi,
how can I set PI plate resistor trimmer in d-style amp?!

Thanks

Hi,
Are Voltage value in this schematic correct for any custom reverb?!

Up please!!!

I think that this PS would be OK.
What are you think?!

Ok, I hope that is right! the impedance of my OT is 7500Ohm Plate voltage 320V Load lines in attachment!!! Power in watt 11,445W Bias of the 6V6 = 28mA 80% of the max Control grid -18V Screen grid voltage 312V screen grid dropper 1K screen grid stopper 470R 2W Cathode bias resistor 330R 2W or 270R 2...

Could you tell me some circuit simulator for mac?!
I would like to test some configuration of this amp!

Thanks!!!

No, i would like to use only PA stage of this diagram with preamp and PI of JM...

Thanks 10thtx!!!

I'll try to use this! =)

Here some specifics of my transformers...
OT
15W
6200ohm

PT
250V Plate voltage
I don' know intensity current!

and here schematics with 275 0 275 PT ... with specifics near to my PT

thanks

The amp is 15W...
I use PT and OT of a Ibanez TSA15H ...

I could use this PA for my new amp!

I don't know what is 150pF cap on the pin1 of the PI... it can cut high frequence?!

I think that one changes could be a cathode bias or mixed bias instead of fixed bias...
usually small amp with low voltage use this.
But which values for screen and control grids and for plate?!

HEEEEELP!

Other changes on Power Supplies...

What changes?!

Thanks!

I would like to learn and I want to build a good amp...

to discharge cap filter when the amp is in standby...

Ok, but It is my first amp and I would like to spend a little...
I don't know the effect of the resistor of the grid of 6v6...
How should I calculate the value?!

this power supply?! it's right?!
