Sorry @Pars i wasn´t thinking right..What i have is the CFA2... My mistake..

Hi @Pars I think I have some spare boards with the latest version, that has the servo completely out of the audio path, as Kevin said. Tomorrow I let you know. Best Tiago

@kevin gilmore : For when, the version of the SS Dynalo ,with the current mirror in the servo,like you did for the cfa? ? Thanks a lot

Can i use 2sa1930/2sc5171 instead of mjf15030/15031? Thanks

Can i use a 500 mw CMF55 in the 1 ohm position,if i only 4 pin xlr in the output?

Thanks Pars. I could maybe ,put some heatsink in it ,to avoid heat issues. Another question ,if you guys can help. Can i use BC550/560 if i only go up to 22v in the power supply?

Guys could use i use normal mpsw06 and 56 in place of the pzta06 and 56?Maybe soldering the colector leg only to the big pad? I got many of the mpsw and the pzta are always off stock in mouser...

I am using an adapter that Kevin made specially for them ,so it´s ok .

i have been using for the input of my dynalo some 2sa1349/2cs3381,that i bought from Justin at a very good price. Even with no matching,they are working very well

It will be for the ss dynalo and i will be using 22v secondaries transformer. yes, i have some small ones more a less the size of those.It´s just, if i can use those, i wouldn´t need to do more holes...

Guys ,do i need heatsinks for the grlv, for 20v, to use with the dynalo?If yes small ones will do? Thanks

What is semi foo foo in this case Pars? Yes i know i can use anyone but was just wondering what teh guys thought was best both in musical and technical terms. I was thinking in use nichi ukz. Thanks Jose

Guys for the 100uf Electrolytic in the ss dynalo what would be the best capacitor to use in that position?Both in technical and musical terms combined?or doesn´t that matter at all? I saw some of us use nichicon ufg,ukz but i want to know if there are different opinions. Thanks

Oh yes ,of course....Thanks Kevin...But my Dynahi without the opa445 is definitely a no go for me...

Will this work on a ss dynahi or dynalo?

Understood Thanks! Yes, i will try this and see what is the result.Thanks

You´re right.For some reason in my mind i was with the idea that that was jfets... yes,but 50$ for that low amount of jfets is what i call expensive ....I know they have to be matched and etc...but still..But i guess that is the price these days. Obrigado Tiago

Nice! @mwl168 did you soldered directly a wire to the wiper pin?

No problem. It's not risky if you know the right source.. Justin just bought a pile of new old stock of jfets. Anyway, if you could sell me jfets to replace the that 340 I will be a buyer. If the price is right. But anything pm me. Thanks

Hi I have a BOM for ssdynalo smd version here that i can get you. I also have ssdynalo boards here if you want ,but is the through hole version, but also i have here some through hole mpsw56 and mpsw06 that i can spare if you are interested. About the grlv you have the formula to change the output voltage here : I also have the schematic and the gerbers if you need it .

Thanks Pars!

Guys can i use this https://pt.mouser.com/ProductDetail/Vishay-Dale/RN60D5600FB14/?qs=sGAEpiMZZMu61qfTUdNhG1jRaYe8f2sLpmQ2711SR7M%3d for the 560ohm resistors ? It only has 250mw of power rating..Is that ok? Thanks

Guys( the ones that already built the amp) ,what do you think in comparison with ss dynalo?

Yes, you are right. But also as you said before MLCC with more than 25v is hard to find...

You have tantalum ones at 35v. I bought some of these to use in this amp and also in the Grlv.
