A "Better" idea for an attenuator
I've been following the "Airbrake" thread. It looks as if the Airbrake is shunt attenuator - fixed series resistor and switchable shunt resistors (using taps of a big WW). These work fine - my hi-fi preamp has one. However the impedence changes with each switch position. If we built a ladder attenua...

Re: Airbrake schematic or layout
Could I please have a copy of the schematic as well? Por favor. Also, I have a THD Hotplate. Does the Airbrake sound better? My Hotplate injects some strange sound on sustained single notes. It is hard to describe, but the low end seems to drop out and the sustain sounds modulated - kind of like a v...

Re: External biasing wiring?
Putting together an express and have some questions. I have an 50k 10 turn external bias pot that I will be mounting similar to the komet.The pot has three leads one on the end of the resistor,one in the middle of the resistor ,and the last one goes to ground.Does the top resistor one go to the 47k...

Re: Transformer sets available.
Hmmm... I am building an Express, so I assume that the iron I got from you will work fine. However, I was thinking that having both 5k2 and 6k6 primaries on the OT would be nice. Does anyone know how soon will Moose have more (of the new iron) available? If it is going to be soon, I would rather hav...
