Mr. Dayanand is nice person. But they do bulk orders, But he is considerate if one says before hand if he is a student or a hobbiest and only 1 or 2 qty is required. Any one who is in manufacturing can understand it is little time consuming to make special one or two custom pieces.
he did gave me the quote for my amplifier but I have yet to decide as specifications/values for my transformer is not yet fixed.
All my transformer requirements for my DC SET Monoblock were fulfilled by FM @sadik . He got it made for me with a reputed company Silchar Technologies who also supply for reputed international manufacturers. The built quality and tolerance are spot-on. No complaints with initial assessment.
I will start my assembly by end of this month ( hopefully).
Recently, I purchased a toroidal transformer from GTech Audio, Tirupur, TN. Though, there are plenty of vendors where we can buy toroidal, many refused to make based on my requirement. Gtech Audio was super friendly, accepted to make for my spec and delivered in 7 days.
