I have a Bada PH-30 amp that I got on Ebay. It came with 220 v. transformer. I got sick of lugging out a step-down transformer (Big, noisy, looking like an early Edison prototype), and took it apart to look for a 117v (or so) toroidal. Suffice ity to say, I didn't get it done, and the amp has sat in a basket (literally) for the past four years.
I havce also been in the market for a Gainclone kit. TodayI was looking at one at 8Audio's "mall" site. I noticed that the transformer they offer for their dual mono 3886 chip amp kit had the correct specs and dimensions for the Bada. That got me top thinking. Upon comparison of the Bada circuitry and the photos of the completed 8Audio chip amp board, it struck me that they were somewhat similar in appearance. The Bada I.C.s look exactly liker the 3886s ( and, I realize, and a thousand other op-amp sized chips).
The chip amp boards are dual mono, and the Bada is stereo; the 8Audio power supply components are on a seperate board, while the Bada has everything on one board except a few caps and resistors on a tiny board with the input selector and RCAs. My level expertise is not such that I can determine whether the the Bada Board is the analog of the three 8Audio boards.
Does anyone have sufficiant familiarity with the Baada PH-30 circuit to say whether or not the Bada PH-30 is a chip amp Literally speaking, of course, it emplys chips; what I mean to ask is: is it of the same circuitry type as the original GainChip and its progeny?
