I ordered an Avel Lindberg Y236803 500VA 35V+35V Toroidal Transformer from parts express and two amp boards, soft start and power supply from Mirand.
Hi. Thanks for posting this project.Can you explain the reason why you're mounting a card on the left-hand heatsink? I'm not an engineer, and I have precious little DIY experience.Regards,Michael
Hi Robert,As a fellow diy hobbyist, I'm just here to cheer you on. I've got a few dozen projects under my belt and in the last 2-3 years it's almost universally been amplifier builds (courtesy of diyaudio, etc...). The Takachi enclosures are very nice from a fit and finish standpoint, and I would reserve them for low bias Class AB designs mostly. I have a few Class A projects going and all of them need beefy heatsinks which although the Takachi HY series (even the 6U sized ones) have heatsinks, they are not very deep at all and hence their heat dissipation is quite low. I think for your project, you'll be fine. In fact, I am looking into Takachi for my next amp build, although the Modushop enclosures really make my life easy because of the baseplates you can order with them. If you need some inspiration, send me a pm. Hopefully you are surviving in hectic sunny Chennai. Eat some dosas, idlis, sambar and chutney for me! Michael, I think Robert has a pair of amplifier boards and he has shown you just one of them mounted thus far. My very best,Anand.
