Good morning all!
I just heard from Peter at Audio Sector and he's currently selling pcbs only. No worries, I'm fine with buying my own parts. I've heard nothing but good this about this kit but might as well make the opportunity to make a few improvements.
What you your thoughts on ways to improve these kits in terms of components selection? Better capacitors or diodes, etc. I have experience buying components to spec but no idea how they might affect sound in audiophile equipment.
Also, who the hell is selling lm4780 chips right now?! I can't seem to find them anywhere
Thanks everyone!

Hello,
I have the lm4780 you are looking for. I bought it from national semiconductor in 2011 or 2012 . I'll contact you if I can find a way to ship it to you for a fee. However I also have a small amount of LM4702 , LM4781 , LME49830 , LME49810...All original and new..I'll try to add pictures if you want.

Hi,
I tried to contact Peter via his website twice, but no reply...
I have 4 LM4780 chips that I want to use to build two bridged/parallel monoblocks and same as you, I'm okay with buying my components. Already built two monoblocks with paralelled LM4780 chips and they are sounding great, used everyday.
If someone comes up with schematic for bridge/parallel Peter's boards that would be great...
Sorry to hijack your thread, but I would be interested in any tweaking as well.
Thank you all!

Unfortunate then that there are so many great builds and guides out there using this chip. What then is the current state of gainclone building? What current production chips are people using in their builds? If I knew the part number I'm sure I could find some projects to go off of.
7294. and others are still in production.
As the world shifts to Class D, buy and keep some extra as spares, whichever device you buy, as Class AB are slowly being discontinued.
The best current solution seems to be discrete amps, no transistor shortages, yet.
Or Class D.

I uploaded it to external location because the size of the photos is large.
looks great! I'll send you PM and we can talk about prices

Hello,
I can only use western union as a money transfer system. My asking price for each of the LM4780 is $40 USD. I will learn the international shipping prices from the postal service on Monday . As a result, the chip price + the transfer fee = the total price will be determined. Those who want to buy under these conditions inform me of their country and region codes. Have a good day everyone.
(I apologize for the delays as I have never sold internationally before.)

I have a pair of the original output board and rectifier board, part built with lm3875t Panasonic fc, caddock resistors
£40 Inc shipping from uk gotta be less than parts cost

Dang, wish I'd seent this before I bought all this **** this morning lol oh well it'll be fun to build
