RE: Questions about 6BG6G amp build Grommes 216BA - Pic

Posted by Michael Samra on May 27, 2017 at 08:59:18:
What I was saying was,if the choke is totally miscalculated for circuit,it can change the impedance of the power supply and how it relates to the load that it is feeding.This can cause loss of dynamics and or freq response.It happens mostly at lower frequencies like 120hz.
I figured this out years ago when I took the choke out of a Citation 2 and put it in the Golden tube SE-40 and we are talking two amps that draw close to the same current. When I put the choke from the Deuce into the SE-40,everything got muffled and dynamics just washed out. The Choke in the SE-40 was a bit larger,but the choke in the Deuce was like .7hy but being both amps had plenty of capacitance of either side of the choke,I didn't think it would be a big deal.
As I have said,I didn't mean to imply that it wouldn't work however,just throwing a high inductance choke that looks impressive into a power-supply can cause issues that one might not expect.That's why I asked Pete if it was the one already designed for that circuit.
I'm one of these people that believe in measuring the basic fundamentals when you make any electrical changes.
