asuslover, thanks for the quick reply. My thoughts are to buiild this as a stereo versus mono block. Is there a torodial power transformer that can work for two boards or do I need to consider mono blocks?

[asuslover]

the first 2 listed are 600va, should be good for 2 channels , the third one is 300va, good for one channel only, but it's up to you the way you will build it.

Hi Shaan, any pics of finished amp...wanted to estimate heatsink requirement

 

[fencki]

hi.

thx

 

[shaan]

Hi Fencki.

Not yet. I am expecting them by 13-15 February as previously mentioned. I will update here as soon as I get the packet.

Thanks for your patience.

Hi Kamal.

Mine is a naked setup so no pix of a finished amp as of yet from me. But you can use a 300mm x 100mm heatsinks with 30mm fin depth for one channel. You can contact the following website for heatsinks with any dimensions for a custom design: Akash Heatsinks

Humm... I have 204 X 100 mm heatsinks with 42 mm fins



Can this work for single channel?

 

[shaan]

Yes as long as the fins are outside the chassis and continuous power output is ~100-150w. It may not be enough if your plan is to push the amp hard into 4ohm.

Got it

Hi shaan,

Sent you a PM reply to your email. Ship to Canada address. Do not ship to Mexico address.

Thanks,

Myles

 

[shaan]

Hi Myles.

I did read the PM but was busy with the small boards that just arrived so couldn't reply. I will cancel previous invoice and send fresh one shortly.

Thanks.

Hi shaan,

I do not think you need a new invoice, you just have to ship to Canada and not to Mexico.

Or am I not thinking correctly.

Cheers

Myles

 

[shaan]

Shipping charge for Canada is higher than Mexico. Hence a fresh invoice.

 

[Kokanee]

My Bad!!!!

 

[shaan]

Fresh invoice sent.

Transistor matching

Is it possible to provide matched Q1/Q2 and Q9/Q10 as well?

Hi Shaan, I see the BOM values for transistors are in B classification, to what range are we expecting HFE's to be and how close do they need to be matched.


Also how bad it would be if we don't use matched transistors. If I buy in 100's, not sure what will I do for with the rest of the transistors
