Bespav Posted May 15, 2016 Report Share Posted May 15, 2016 Hi, everybody! I'm novice here and signup being impressed mister Kevin Gilmore designs. First of all - thanks to him for making designs opened! Now i'm thinking about building Dynahi at a different manner than author. The main concept is to put overall amp in a comparatively small case such 3209: http://m.ebay.co.uk/itm/3209-class-A-Full-Aluminum-amplifier-Enclosure-AMP-case-both-side-heatsink-/271986781371?nav=SEARCH So, PCBs must be rerouted. Here i want to offer another building idea, best to understand by photo and renders (for understanding dimensions - caps are 18 mm diameter and 35 mm height): There are several benefits in such layout. 1. Input stage (further - IPS) and voltage amplification stage (further - VAS) are separated from output stage (further - OPS). 1.1 So we can easily swap IPS/VAS board based on BJT/JFET, balanced SuSy or single-ended, SMD or throughole without need to demounting OPS from heatsink. 1.2 Each of the board are comparatively small and can be done with better shielding/decoupling, and even on a 4-layer PCB if needed at a low price. 1.3 Further improvement via changing small IPS/VAS board at a reasonable price. I suppose, that OPS board can be splitted to two boards under 100x100 mm and prototyped here at a very reasonable price: http://www.pcbway.com/pcb_prototype/ This thread will contain all PCB gerbers/projects or custom numbers at PCB-providers. Any opinions/suggestions? Quote Link to comment Share on other sites More sharing options...
luvdunhill Posted May 18, 2016 Report Share Posted May 18, 2016 Looks interesting, I would probably build one. Quote Link to comment Share on other sites More sharing options...
