Things got out of hand.. (large!!).

Dear All,
Last weeks Iâ€™ve been busy making â€˜prototypeâ€™ boards for the all new amp Iâ€™m building. I wanted to test a few things, so I wired up some stuffâ€¦ And as always it became a â€˜beautiful messâ€™ I would like to share.
First impressions. AWESOME!! This is the first all DHT amp I have breadboarded with a low DCR (not low C and H yet) PSU.
FYI, this is an integrated Aa (series battery biased) cap coupled to VT25 (cathode bias) cap coupled to a 300B (fixed bias). Aa and VT25 heaters are supplied via a VCCS, Aa is loaded by a CCS/resistor combo, the VT25 is choke loaded.
Thanks for looking and sorry for the bandwidth!!
