PeeCeeBee V4 GB!

Shaan ,
before I order parts which components need to be changed for 42Vdc rail voltage ?

 

[shaan]

thanks for all you have done. Excellent job. Do you have a bom for a +/- 42v version?

Add the last two to my order please Shaan. That will be a total of six for me. (An extra $16 if I am correct in assuming it shouldn't add any to the postage cost?)

Daniel

[cats squirrel]

Less than three weeks for the PCBs to arrive. Let's start gathering the parts.

Here is the BOM for V4.

you are missing the two LED's.

 

[asuslover]

Any reliable source for 2SK1058/2SJ162?
thanks

 

[shaan]

Uploading corrected BOM in a few moments.

 

[shaan]

V4BOM-REV1

Here is the revised BOM. All parts in the previously uploaded BOM remains unchanged. This BOM adds two standard LEDs to the list.

In case you are already using the first BOM then just add a pair of 5mm standard brightness Red/Green LEDs to your list and all is well.

I can get you a few for $7 a piece and ship along with the PCBs for no extra shipping charge. These are available in my local market.

All online sources I could find (except aliexpress and the likes) currently show none in stock and the next time of availability to be September.

Check this out. BUZ900P/BUZ905P available from RScomponents Romania. You can use these MOSFETs in this amplifier.

BUZ900P

BUZ905P

p.s.- they seem quite pricey.

 

[bambadoo]

Just be aware of a lot of fakes around (2sk1058/2sj162)
Suzy's Blog: 2017

I might have some spare in the bin somewhere after I have finished the V4
