Indeed, it’s a LT1085 based power supply, with Roederstein filter cap on a recycled heatsink. Actually parts from my parts bin that otherwise never get used.- Ferrari

Thanks for the kind words gents ! @ Forte I’m afraid that we are a bit too late for that. The perfboards power supplies are no longer sitting on my table but are already built in one or other devices like this M3. Taking the amp apart, just to take a photo of the perfboard...- Ferrari

Is the Dynalo still a good choice?
From experiences, closely matched and thermal-bonding of the input JFets does contribute to the stability and help to lower the DC offset of the amp. (not only on this build but generally on all the amps I have built in the past) I'm not sure about the tiny heatsinks used on the output...- Ferrari

Is the Dynalo still a good choice?
The unstable problem of your previous Dynalo build on a self-etched PCB (as you posted in the other forums a while back) has probably to do with the PCB layout itself (signal routing, LCR characteristics…). Your recent Dynalo is built on a professionally made PCB, which has been proven to work...- Ferrari

Is the Dynalo still a good choice?
Here is a budget Dynalo with power supply in one box I'm building for my brother, gain is setting at 2x (for Denon D5000). The power supply includes ~10,000 µF Sikorels (my favorite PS capacitor). Most parts are from my parts bin, from there the resistors cocktail.- Ferrari

EHHA Rev A - Interest Thread
BloodInside, using the 2-pole AC plug (Class II Euro-plug), as common in our Dutch living room, there is no need to worry about the AC ground (similar to other hifi-equipments in your room… just skip it !!!). Appliances in your kitchen or bathroom areas are another story...- Ferrari

Quote: mb3k, good to see you back. It seems to be that there is not a real new case styling in amps at all recently. However so many thing is possible in DIY regarding the used materials, colors, the shapes… The inspiring work HF-member zkool448 is worth to mention. ...- Ferrari

Quote: Good to know you like it. And indeed, OPTs can certainly make or break the sound of an amp. The only nasty thing about good OPTs (especially custom made) is that they can really hurt your wallet. I recently got a couple of OPTs with amorphous core & silver wires for my...- Ferrari
