[size=medium]Second generation PPA Diamond Buffers are here![/size]
for information about them start browsing the thread from the last pages
relevant information regarding 2nd generation buffers starts at this point..
For the newcommers: last year I have developped Discrete PPA Diamond Buffers as a cheaper DIY alternative to LaRocco Audio's Triad Diamond Buffers. They were based on Perander's QRV-05, which is basicaly a common implementation of the cirquit known as Diamond Buffer. After the success of the first run of these kits and sets I've decided to develop even better ones. I worked on them in my spare time with kind help of ppl and now I'm almost done. The new generation buffer prototypes were found significantly better when A/B compared to the older ones - that was the goal after all! Now I'm working on getting them ready for you. The buffers will fit PPA v1.x buffer sockets and are much better alternatives to commonly used Intersil HA3-5002 buffers. They will come again either as kits or fully assembled sets. Kits will include all the necessary parts and buffer boards with surface mount parts already populated on mashine. Assembled sets are fully tested & working plug-in modules, all you need to do is open your amp, remove existing buffers from the sockets and plug in the new ones, it's that simple.

although I don't own any PPA and never had, this thing was bugging me for a long time
do you remember peranders QRV-05 smt diamond buffer? my version is in fact his, just with some modifications like removing unnecessary components and output stage little like Gilmore Dynamic..
dimensions: 1" x 1.2", sitting on pin headers in PPA's buffer sockets, should fit well and on top of that shouldn't be taller than main filter caps..
