This sad news was shared last week in another thread on this forum and it is indeed very tragic. He was a very nice person and very very knowledgeable. I came to know about him recently from this forum and he has repaired many audio equipment for me right until the time he became ill. His knowledge is much more than that of the authorised service centres we go to in Bangalore, Technicians from authorised service centres are fairly useless and always used to hesitate when I talked about repairing old equipment, however Johnson said that he can fix anything that is an electronic item and he proved it, even when circuit boards were broken he would build a new circuit board from scratch. Even Lizner did not have the confidence Johnson had when it came to fixing stuff, however to be fair to Lizner who I have never met and only spoken with him on the phone he sounds like a fairly elderly person, so his hesitation is understandable. Johnson will be greatly missed.
