Headroom Millett Hybrid Mod Maximised (Work in Progress with Pictures)

[applegd]

This has been on my To-Do list for long time while I helped some of my friends and did the similar things multiple times on others' Headroom amps . Finally I am getting some time to mod my Headroom Millet Hybrid Desktop amp.

Action Item List:
(1) Check whether it is necessary to re-cap and upgrade little bit
(2) Make Millet tube section mod easier to allow installing/removal of tube socket board without soldering.
(3) Enable Headroom amplifier module rolling capability using gold plated socket and pins.
(4) Enable OpAmp rolling (without soldering) capability on Headroom Amplifier module to take advantage of the latest OpAmp chips including Burson Audio Vivid Fully Discrete ones, OPA2828 etc.
(5) Upgrade the stock Headroom module (From "Desktop" module to "Max" module class/level.)
(6) Add LED light support to the tubes.

Just wondering whether anyone did the same things in the past 19 years?
