Send me a message or ask a question, but please read my ADCOM FAQ first.

  • I am not doing repairs; I only do full refurbishings of GFA-555, GFA-565 and GFA-585. Details and prices are here.
  • I do not sell parts, or parts kits, except for what is included with my circuit board kits.
  • Support is billed at $75/hr beyond the 30 minutes included with purchase of a circuit board kit. Please see my support policy for more.
  • Please don’t ask for help troubleshooting your equipment, unless you are installing one of my products. I get more emails than I can handle. A better option is to ask your question on DIYAUDIO.COM or the Adcom Audio Enthusiasts Group on Facebook. I am very active in these communities and I may chime in there. Go ahead and send me a link to your post asking for advice.
  • International shipping: I ship internationally via United States Postal Service only. Send me your address and I will calculate shipping costs and send you an invoice for the items you want.
