OMG , that is quicker than I made my pre-built.
You should of added a Vbe trimmer to your layout.
Give credit to Harbinger , this is not my design.

Mine is ready to throw in the box.
With just 2 devices , mine is the louder of any the OEM 2.1's in the house.
Has much snappier bass than a Logitech bridged LM3886 Z series amp.
And twice as loud .... outpaces my satallites.
I am so pleased , I'm about to build a second one with 4 OP devices.

That is pretty much what I bought for 9$ usd on Ebay.

My bigger one will have infinite phase adjustment.
I'm a sub Whoore now. bigger one has 2X D2029/B1347 , (below)
peerless beware !

I' glad I diy'ed instead of
spending 179$usd for a parts express stupid plate amp... China POS
I have 2 way better amps for my 10/12 " subs.
The 10" I'm hearing now is impressive. I can "blow the curtains"
with my keyboard pictured before. C1 / D1 (33/37hz) notes makes my hair blow
where I sit. Polk POS amp never did this , same keyboard.
I'm actually impressed by the polk OEM sub driver - I can't blow it.

NAD 2700

My NAD 2700 project. Just replaced the relays and cleaned up all switches, connections, and pots.

I really like the sound of this one.

 

[ostripper]

Class G tracking amp with 60V/95V rails. 2 pair toshiba 1302/3281's and
a third pair for the tracker. Input stage looks like a Sansui with 2 stage LTP.
Never seen this one. Electrotanya has the schema.

Input stage was quite liked by my people. Tracking class G is more "audiophile"
than a "dirty switcher" (Class H). Must belt out quite the peaks !

Here's something I originally built around 20 years ago, but renovated/finished off during lockdown.
Dual mono, Class A, 8W/channel into 8 Ohms (Could be biased for more, but that's plenty for the 97dB@1W "Dallas II" horn speakers I built).

Thank you for the pleasure of witnessing a good scratch build. It’s logical, original and clean.

Don't know why, but it reminds me of K9 - Dr Who's doggy robot
