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

How much are the PowerClone PCBs?

 

[veteran]

PoweClone - about 15$ for one board.

I ordered 50 gold plated LM4780 PCBs if somebody is interested. They will be ready for about 1.5 week from now. Price for one - 10$ (PS included, more space for 10mm snap-in capacitors).

Hello Damian

I'll take 2 PCB's if that's OK

$20 + ? to sweden

Thanks

edit: the gold plated LM4780 ones

 

[imackin]

I would be interested in 8 of the LM4780 PCBs

thanks

hi veteran,

i would like to have 10 of those boards please..

thanks,
tony

How would you like payment for the LM4780 boards?

 

[veteran]

I can accept PayPal or standard bank transfer.

Hi

any chance to get a power clone with LM3886 ICs?

 

[veteran]

Maybe... but I think that LM4780 is more suitable for power clone configuration. You will find two LM3886 inside and connecting them parallel/bridge is easier.

Please count me in for 2. I would like to use Paypal, please send payment instructions.. I have built a ZEN V9 with your boards and am very happy with the results. Thanks again.

 

[veteran]

Boards will be (finally) available after this weekend. T3447ml, just contact me.

If somebody will be interested - I can also order more LM4780 chips and 0.22R/3W/0.5% resistors for parallel configuration.

Hi!
I would be interested in 2 of the LM4780 PCB.
Thanks.

Boards

Im interested in buying 6 boards and possibly the LM4780s to go with them. Contact me with pricing and shipping to usa zip code 55337 at postalrat@yahoo.com.

Thanks for making the offer available.

May I ask you how much is shipping a couple to Italy?
Thanks

Hi veteran,
Isn't there an option to adopt a bridge setup? Or even a bridge-parallel setup ...



Thanks

 

[veteran]

Yes, this is possible and quite easy. For bridge configuration you will have to use one (stereo) boards per channel if your source already have symmetrical signal on output. If not - you have to use external inverter (like OPA1632).

Shipping to Italy - about 8$ (including PayPal fee).

 

[veteran]

Example of symmetrical LM4780 amplifier. If you need more power - output stage can be replaced by two boards in parallel configuration.

Many thanks Damian,

I'd take 2 LM4780 PCB's if that's OK with you, either the gold plated ones or the tin plated. Prices? (besides the $8 for shipping to Italy, of course ...)
The additional resistors for paralleling etc. might be welcome too
Furtehrmore HOW TO ORDER? (I'd pay via Paypal)

And now forgive me: PDF is clear about the Bridge config. Quite easy, I'd say, even for an absolute novice as I am ... but do you also have any like schematics for parallel and/or parallel-bridged config?

Thanks again
Daniele

 

[veteran]

Just make sure that there is no R3 on every board and place J jumper.

PayPal is OK. Boards are only in gold plated version (10$ each).

Hello again Damian, we talked over email some ~2weeks ago but it seems that there is some trouble with the mail? or did you get my answer?

Many thanks
