I read the following in another Quickie thread - a snip of a Doc B qoute:

"....I was using a Quickie that had the Speco transformer mod for high impedance headphones, which is about 3dB down at 80Hz, as a line stage..."

Does this mean that were I to use my headphone mod Quickie as a line preamp I would get responce that was lacking in bass?  Is there any fix for the drooping bass responce from the output RCAs in a Quickie with the Specos? Bigger caps perhaps? ...or rig a switch to take the Specos out of circuit when using as a line amp?

Yes, I believe that is exactly what it means. To restore the deepest bass, either take the Speco out of the circuit, or replace it with a transformer that has more inductance at small signal levels.
