Even scarier

How sensitive is this supply to external capacitance? It seems low-Q capacitors such as film bypass could cause lower performance. Has anyone looked into this?

Apparently HD800 cables are not bunny proof why couldn't the bunny have worked on the power cables not a few feet from the headphones?

I have some, but I am not sure how accessible they are. I am on vacation in FL, when would you need them by?

Once you go connectors, you don't go back

Cool, I would be glad to start the layout. I have a specific width in mind though, and would not have the rectifiers or bulk capacitance on the board, so we might have slightly different use cases. That being said, sure, I would love the models (and any answers you have arrived at)

Has anyone done analysis of the circuit to see if any the semiconductors could be replaced with SMD and what resistor power ratings could be used? I would target 1A output at +/-23VDC output using a 20VAC transformer as input.

KG: can I get a link to the most up to date schematic?

Here is a low pass filter board, utilizing above discrete opamp

I have a real simple question maybe someone can help me with. Given an opamp connected as a buffer, if instead shorting the output and inverting input, I place a resistor here, this should have the effect of bandwidth limiting the buffer effectively, correct? How can I calculate the effect of this value on the overall bandwidth? I can't seem to find this discussed in any detail in intro texts on opamp circuits.

Here is a PTFE trimmer measuring 1pF

Oh yeah, it does much lower. The caps are mislabeled.

Am I doing it wrong? I hope I don't have to start over!

Do you have a supplier for these in the US. It's an easy enough thing to do, so I might as well. McMaster-Carr

I would suggest Belleville washers.

It's alright, you can use the word "voicing".

Burn-in

It would be easier if he could tie the clip to the "bottom" negative rail though - which he can't - unless he floats the scope or uses a battery supply.

The scope readout is adjusted automatically, which is convenient. The P5205 might be a better choice.

I use a Tek P5210.
