Hello vipin
What is price of 12 inch heatsink With post charges

Heatsinks costs around 750
And shipping costs as per weight and pin code, you are from Mumbai, so something about 300 so less

A question.
How do you invert the image for printing?
Base and emitters are not the same.
Thanks.

Updated on heatsinks
I'm not the seller, heatsinks available in Delhi market, I don't own the heatsinks, so don't think that I sell them in 750 rupees and ship it to someone, I did only as shopping assistance, for those who can't visit or don't have time to get from Delhi market

I'm not the seller here

Ok, now we don't need shopping assistance, you just post here seller contact no. for those IND members who can't visit or don't have time to get from Delhi market. May be they do contact directly with seller.

Depends upon the nature of the seller, usually they have minimum quantity requirements for ordering.
Try to find out a local source, it will be cheaper than anything else online available

@ apexaudio

I recently stumbled across this redesign for a B250, is this yours, or someone else's work?

If it is yours, can you please explain the A + B terminals at the input, and the purpose of the Pro terminal at the output?

I imagine it's out there somewhere, but I'm not finding it.

Regards,
JohnR

I don't know exactly, which transistors those are, instead of mje340/350.
But pay attention to the pinout of mje340(ECB), MJE15032(BCE)
