oh that explains I think they are way too stiff "rigid" for your amp if you get paper cones woofers at 8 ohms even 10" woofers size man that would sound magnificent

I have two Alpines type R woofers and they barely move jejejejejeje love your video bro it does motivate me :D

Improved performance with better VAS transistors

KSC3503/KSA1381 could be used in place of MJE340/350 for Q4/Q7 for superior performance. leave the 340/350 in place for predriver duties.
MJE340/350 were used only because of non availability of recommended parts in the local market.
So had to order them online. Received 100 each of KSC3503E and KSA1381E.:) Good for several new projects.

I attached below PDF version of the Gerber files. Congratulations for the work.
If you want to print actual size, select "Page Scaling = None".

Hello mister Aniket

Since I like you layout a lot I'm trying to actually yes "clone" yours to accommodate the parts I have on hand I'm not done yet and I'm really busy this days I thought to show how it looks, by the way I like more the top installation for the power transistors my personal preference :D by the way bro thank you for sharing the file it was really nice of you :)


Regards
Juan

1381 and 1507 are not equivalent.

1381 makes a good VAS and pre-driver low Cob 3.2pF to 4pF, Icmax 100mA
1507 makes a good driver Cob 15pF to 22pF, Icmax 1.5A

Agree,

but these are still better than MJE340/350, originally used for VAS duty. main concern is the parts availability.

2SC3790/A1480, 2SC3788/A1478, 2SC3645/A1415(different package) make excellent VAS devices, but then again, are these available.?

On semi has acquired Sanyo I think, hope they would manufacture these.

Aniket
