Hi all.
I hope everyone is well as can be during the crazy time we're all going through.
The REDD 47 discussions have all but evaporated. I guess I'm late to party.
Now that traveling for work is not an option, I'm finding the time to get unfinished projects started again.
I've boldly (with no EE schooling at all) taken on the DRIP Ultra 47.
Oh boy. Talk about pages missing. I can't wait to feel what 300V feels like.
About the T-pad.
I don't have the model number but here are some notes about it.
Mallory T600 Audio T-pad, 4 Watts (15W Audio)
The range of attenuation (not mentioned in any of the Mallory spec sheets).
Measured resistance of the three (wirewound) sections of the attenuator and found: the outer sections are 600-ish ohms and appear identical, as they should be. The center section ranges from about 1 ohm (max attenuation) to about 12 megohms (min), and has a very steep non-linear taper. The very high maximum resistance implies the minimum attenuation is very close to 0dB.. max attenuation would require a careful measurement. Estimate about 60dB from the resistances..
Would the T Pad listed above work with this build?
Anyone wanting to open up a dialog is welcome.
Thanks all.
Anthony.
