2x60W/1x120W audio amplifier PCB (LM4780/4732)

veteran · 25th May 2006, 03:53 PM

I'm thinking about one more series of LM4780 boards. If there will be enough interested members - we can make them in a good price (about 10$ for gold plated PCB). What do you think?

My LM4780 PCB can work in standard, stereo (2x60W) or parallel (1x120W) configuration. There is a place for MUTE circuit, diodes, and additional 10mm reaster snap-in 'big caps'.

I also have about 20 LM4780 chips from my last order. Universal preamplifier module can be also available:

Damian:

I have a friend who might be interested in 2 or 4 sets of the PCBs (he wants 1 or 2 100+ watt amps).

Regards,
Scott

Hello Veteran,

I would be interested in 4 or 5 boards + LM4780's.
Did you have a groupbuy of boards before? I must have missed it, pity.

Greetings,

Jarno

I'll be interested in 2-4 boards as well, but I have the IC's already

Hi,
I'd be interested in two boards and LM4780s - are still available? How do we pay you??

thanks
Ian

Count me in for 2 boards.

Maybe you could mention how many you need to order for the "good price", where you'll send them to, etc ... ?

I would be very interested in 2 boards, thanks.

veteran · 2nd June 2006, 10:49 AM

I have to order about 60 of them, but if there won't be so many people interested - price will be a little higher. I will wait few more days and we will see

I'd like two. Let me know if this goes forward.

thx,
