Hello DIY addict[emoji16]
can anybody recommended preamplifier design with ton control
Thanks.[emoji120]
Apex A40 + TP2 - YouTube
hello all,
I have made a crc psu with 35 amp rectifier with a provision for heatsink for high power amps or class A amps. it also has a primary side soft start with NTC.
pcb can be mounted on 10x10mm grid holed mounting plate.
Let me know if any one has any suggestions.
heatsink like this https://www.mouser.in/datasheet/2/2/Aavid_01112021_Board_Level_Cooling_Square_Basket_6-1953640.pdf
or

or

An update to the quoted design.
I built and tested the PSU and works well. Plan to use it as a PSU for my main amp. it uses CDE caps and 35 amp bridge rectifier with heatsink.

Hello friends
I just finished the apex a9 circuit boards. However, the 10r resistor in the picture burns immediately. I fed with +-30v dc. All circuit components are exactly the same. Where am I going wrong? can you help me.

FX100 psu with protect.
Hi guys
Trying to get FX 100 PSU with protect pcbs made from PCBWAY. Using Sprint 6 files. When exporting gerbers and drill data I am getting this error, and image generated from gerbers is not proper. Kindly guide what to do.

Try JLCpcb.com and see if you get the same error, likely because it’s a one sided board and PCBway is making a two side? Not sure.
If you get same error click OK and include a note when you submit, they should email you if there is an issue before printing.

Here is the pcb, mihailo.
Where can I found the schematic of this version of the AX14 ?
viki, there are some holes defined on the silk layer S1. if the holes are already present on drill hole , then you can ignore the error.
Otherwise, you have to modify the silk layer drill to copper layer drill, which will be tedious job.

I thought the same, But rendered image was all garbled. Didnt look anything like a pcb.
Same gerber is opening correctly with jlcpcb.
Its quite difficult placing orders . Some Pcbway share project gerbers are not available for download. So have to place order with Pcbway. While Jlcpcb is more cost effective.

JLCPCB is using DHL/FEDEX for shipping, which results overall higher cost.
You can try PCBShopper – A Price Comparison Site for Printed Circuit Boards
for comparing total cost including shipping and decide.
But most professional boardhouse is pcbway, in my experience.

There are couple of pcb's which are 100mm x 100 mm which pcbway is charging 24$, while Jlcpcb is charging 2$ for same pcb. That changes the calculation a bit.
This is first time I will be placing order with Pcbway. But overall review about Pcbway is good.
Thanks for the help appreciate it.

😕 not unless they are panelized...pcbway knows if your pcb are panelized, they will charge more for panels.
go with jlcpcb if you can get pcb at 2$ or relatively unknown 'smart protyping', where I got less than jlcpcb for 10 boards including shipping.
include shipping in total cost...😉

My experience is pcbway takes anything over 100mm (even 0.1mm in any direction) and charges a higher price. I have uploaded exact same gerbers in pcbway and jlcpcb and got the same results as viki_v2 (jlcpcb was much cheaper even with shipping)
For India , jlcpcb doesnt have cheaper shipping option especially after 2020 and some border conflicts. Attached, 4 of my "recent" orders have reached US and will shed some load and return to me in a single packet, I only need 2-4 pcb each proto.
Just 3 USD for US and nearly 18 USD shipping for India does "change the calculation a bit"
I have used "elecrow" for Australia for cheapest total in the past.
Plus anything coming to India from Chinese commercial address will attract customs which is nearly double the order cost (duty is on invoice total) :😉

Sorry if I have missed this but is T6 MPSA92 or KSA92...or either?! Mouser have KSA but not MP
And also the lead spacing for the 0.22R on Prasis board.?
Thankyou.

You can use either, likely you will only find the KSA now days
