Thanks for visiting my website! Despite my desire to expand my selection of restoration/DIY projects and expanding the new HL Vintage Store, I am nearly always strapped for time. This is due to the fact I am finishing my Computer Engineering degree, so have a bit of patience if you don’t hear from me for a little while.
The quickest way to get ahold of me, is to email me directly at: Keith@HallmanLabs.com You may also use this for arranging all hardware/software reviews or anything related to electrical/computer/audio engineering, etc.
Thank You for taking the time to reach out and joining the likes of Burson Audio and Orange Amplification in allowing me to review the top end of op-amps.
