Aleksi,
I'm wondering if you could stop posting pics of your amps.
I look at yours and then mine, and feel depressed!

Very nice I love your work!

Default F5, F4 and BA3FE

Hi, it took me 2 years to finish this 3 projects.
Started with the F5, it was the hardest but it grew easier as I gained more experience.
The hardest part was building the chassis.
Took many tips offered in the forum to implement.
Thank you Nelson and fellow diyers who replied to my queries. It has been fun and they really sound good.

Those are very nice and clean builds (I am aspiring to an F4 one day as a winter amplifier... after the rest of my projects clear up). It must have been a challenge to do this where you are already as space is limited and not everyone there has garages and workshops like we do in the suburbs.

Do you have tops to go with those? Did you go naked (like they are in the pictures), clear, painted, vented, or unvented?

F4 is a good winter amp to keep warm. it gets pretty hot after an hour.

All of them have a cover with vent holes not shown here.

I did not apply any finish for the aluminium chassis. I just sand them down. The BA3 is in a box i got it from local shop.

dropbox?
what's wrong with Diyaudio hosted?
My PC security and protections have diyaudio written in as "allowed".

Default Aleph J, nearly done

I am nearly done finishing my first power amp build, an Aleph J. Enclosed a photo.

I hope to be able to test the PSU tomorrow or the day after. I have bought a cheap 3KVA Variac, but it was delivered without a power cord and the plug is different from a normal IEC power plug. As soon as I get the right one I can slowly bring up the power and hope I got everything right.

I could not use the Peter Daniel PSU boards because the 33000uF/50V caps I had bought did not fit. I hope the PSU resistors will be OK like this.

The unconnected red and green wires are V+ and V-. I thought it best to leave these unconnected from the amp boards until I verify that the PSU works correctly!

In order to make sure my ground star point was not directly connected to the chassis, I mounted it on a piece of plastic that itself is raised about 2 inches above the chassis. There is a wire from the star ground to a CL-60 and then to chassis. Safety earth is of course directly connected to the chassis.

Thanks so far to everyone (especially Nelson Pass!) for your help in making this possible!

A bulb tester is a better way to bring the "untested" wiring around the transformer and PSU up to full voltage.

The bulb automatically lights if the transformer draws too much current.

Using a Variac you, the operator, has to monitor the voltages and currents and smells around the circuits. You cannot do all of that properly and "in time" to prevent damage.

Remove all that wiring and replaced with twisted pairs.
