DAC 90A voltages.
Has anyone got the manufactures service manual for the Bush DAC90A (not the Trader sheet) that can tell me the UL41 voltages given in the manual....anode, screen grid and cathode and any given values of anode and screen current given?
Thanks. Lawrence. |

Re: DAC 90A voltages.
Cheers for that Colin, almost the same as what's on the Trader sheet....trying to do an academic exercise, the figures given don't want to tally up with the curves in the valve data sheets, any ideas?

Re: DAC 90A voltages.
You are right Lawrence, there is a significant difference between the figures given in the Bush manual table and those that might be expected from examination of the valve manufacturers curves.
Any ideas? No I'm afraid not. |
