I am about to pull the trigger on getting the gainclone parts together but I witch chip should I buy?

when i built my gainclone i just ordered free samples from National semi.....didn't even have to pay for shipping.

I got 10 of the LM3875TF
That was sorta cheap of me, though, and i don't highly advise it to people who make moral dilemnas out of everything 🙂

I recommend the TF
The T is a non-isolated chip, while the TF is the isolated version of the lm chip.
Gainclone doesn't run hot anyway, so you won't have much problems w/ heat dissipation, and using a non-isolated chip only adds the headache of making sure its isolated from the heatsink.

in regards to the lead time, NS lets you choose which of their distributors you wish to recieve the chips from. I chose arrow and got them in 1-2 weeks.

The "f" version is isolated, I take it that means that you can bolt (2 of them) directly to the heatsink even if it is connected to ground.

that's correct

Yeech, do a search through the chip amp forum and you'll find many people who argue back and forth.
All I can say is that a gainclone has a surprising sound (when you look at it you think to yourself "THIS is going to make sound???")
The look like this:neutron7 said:
An externally hosted image should be here but it was not working when we last tested it.
I have only used
the TF version of it.
I don't know anything about electronics but made my third set of gc's.
Turns out to be easy to solder some stuff together, following instructions from guys here on the diverse fora and dedicated websites!
One thing I do not understand is why NS would even make a non insulated version? they both cost the same price, and the TF is so much easier to handle......
Maybe some one can explain, maybe there is a quality difference, soundwise or so ??? Or Durability, as the heat gets trapped inside a TF version more than the T ?

I guess that the thing about gaincard is its new bold design, that something cheap and simple can sound as nice as anything else. a true minimalist and KISS. If nobody ever hacked one open and figured out that it is using a cheap chipamp, there wouldnt be so much controversy about it huh?
