Ed,The chassis looks nice. Where did you get it?Thanks,Brad
Ed,No problem. Does your chassis have a divider that separates the PS from the amp?Thanks,Brad
How would you compare the hammond to antek in a little more descriptive language?
@ ebag4 , also is it 18v or 15v secondary's ?Edit , I saw an earlier post that had the model # (15y)
Hi eBag4If I could, I would like to make a suggestion tip that was given to me by Rick Schultz, and to which I implemented in my own SS amps.Remove that large ferrous metal bolt and nut running up through the transformer and replace them with a plastic bolt. This made a very obvious difference to me for the better.If I recall correctly, it brought out more clarity and detail in my system.I should also add that I got rid of the large metal plate on top and substituted a piece of 1/8th inch plywood.
Hi everyone--I got my second Folsom 7297 amp, which uses the current version of both the antipole and amp boards, finished on Friday! Once again, I would like to thank Jeremy for offering them again, and also for tweaking the design of both boards.After a rough set of mistakes I made on the first build, I wanted to challenge myself to have an easier time putting together another one and possibly improve on a thing or two over amp #1. Maybe even have some fun in the process... I probably wouldn't have bothered taking on another one, except, despite all the uphill battles at getting the first one to work, it sounds damn good. So...Onward...This one uses Folsom's updated BOM, with the exception of the under-board bypass caps and I also went with the original TI transistor instead of the ON part. The biggest substitution I made was using the Antek 200 VA transformer instead of the Hammond on my first build...Try as I might, I could never eliminate the hum completely from it, which was annoying because otherwise the amp was so good. Imaging and detail are just scary good...I also incorporated a Felix line filter in front of the transformer primaries. I don't know how great of difference, good or bad, it made, but man, I will say the 3d imaging I am getting--even early on--from this amp is amazing!!It has been playing almost continually since Friday night, and has really smoothed out since then, with the bonus of an absolutely black, silent background when music isn't playing So here are some pics...
limits, what size enclose did you go with, L / W / H ? and Brand?
I am in the process of ordering my parts for the Folsom AMP.... I am a total newbie at this , I have built other audio related things but nothing like an amplifier. I may be relying on this thread a little to much during my build, only time will tell. I went ahead and splurged on the case and got the same case limits used, they do look nice. For my second question.....As far as the heat sink is concerned what size should I be aiming for? Whats the deal with this aspect of the build?Thanks.
