Tube Amp Archive

Will try out in keynote and let you know.
a) you dont need to reset it. Just change the values and recalculate.
b) This has vbscript code.....not sure if that goes well with Mac.

Need your inputs on this. PLZ. do not use it for actual modelling. This comes from a guy who knows nothing about making amps, just some calculations that have been put in an excel.

Here's the excel. Please note that most, if not all, characteristic values (Screen idle current, max power dissipation) are wrong. They need correction. The good thing is the %age cathode resistor variance and the corresponding power dissipation. So if the model tells you you need 250 ohms, but you ...

AFAIK, the cathode voltage is to be decided from the datacharts on the basis of desired bias right? If yes, let me know. I have a excel model for this ready which I can put up here and can be tweaked as per inputs from experts. pacifist Good thread! Cathode biasing (of power tubes) is a subject that...
