Is it the tssa v8?I'm glad the cold weather has come, I can take out my 160 Watt "radiators" with 4.2 A bias
Warming up to a new week.
Here in the weekend I looking on a amp project I started before I got sick.
It is a 2 channel board based on my gain module design.
It is a complete amp in the sence it only need a transformer anything between 2x24vac to 2x35vac in any power rating between 200 to 800va.
It has build in softstart, DC blocking for transformer, DC protection of speaker.
Output bias current can be adjust to as low as 20mA and up to class A (with limits of course)
In 2 ohm it should be able to handle 250W for 1 second. And 100W@8R and around 200W@4R with 35vac transformer.
This means in cheapest form it can use a bottom plate of 3 to 5 mm as cooling in close to class B or a heatsink for class AB/A.
I do not believe that a complete very good sounding amplifier can be cheaper. It is 2500€ amplifier performance.
I was just doing a quick price calculation of the board.
What I have in mind is the following :
If I can sell :
10pcs - 450€/unit
20pcs - 400€/unit
50pcs - 350€/unit
Payment of the project could be 50% cover material and 50% right before shipping.
That is a safe/conservative price meaning that is a maximum price.
I will go further and finish the design if it has interest.
It is a fully tested amplifier. Customer only has to install power transistors, add a transformer, add iec inlet, add rca and speaker binding post, and mount it in a chassis or on a plate.
If the chassis is ready I would reckon that even a newbie would be able to get it assembled in one day.
Let me know if you all think of the idea. You can ask pinnocchio about the performance of my amps.
Also if you think it is a dead trap.. Let me know.
Of course it has limitation. The is 24.000uF on board and it cannot be extended f. Example
But still it is very good. Maybe 90% of the Mirand A1 v1. 2

It’s actually a good idea to be able to make an integrated amplifier.
Maybe an option to add a simple preamplifier with input selection using simple LCD or manual rotary switch as an option board. You had already started a simple preamp, maybe it would be great for an integrated amp? Just a thought...
All the best!
