Sorry, Troy swiped the last ones.
However, I could send you Anders Email so you can ask him if he can make some more for you. It will probably cost you a few more $ but probably not many. And who knows? Perhaps you want some more personalized badges for other stuff in the future

Do you still have the MJ21195/6 pairs that you posted about way back when. I see that they are in stock at DigiKey, but you said you could do a better price and I have two stereo chassis to fill at 3 pair per channel.

Why do you have to show them if you got no time to ship?
Just to tease me/us?
🙄
Actually I posted earlier that they were free to any takers who would pay shipping.
I got a couple of replies and "just" got around to taking the pictures of this one. First delay was getting another camera. Now I am starting to move out to the garage in my house pack up and snapped the pics.
I will have to go back in my old email to get the names of the people who wanted them to see if they still do.
I started a job with an Engring dept of 8 people 6 months ago. It's now me and an assistant left... Can you say busy?!?!
I have that one and 2 "flat" or "normal" sinks that are about 6-8 inches wide and 10-12" long. Enough for a low biased KSA or a high biased AB.
Picks of the other heat sinks soon. But again, I had takers who wanted pics and I am just getting around to it. If they decide not to pay shipping cost to ... where ever, then they will be up for grabs again.
Ok, this is officially the most time I have had to be on the forum then the rest of the month combined...
But being busy makes the day go by and Troy a happy boy!
Side note, I have everything to build 3 stereo KSA-50 clones... EXCEPT TIME!!
I hope to build at least one before I die, loose my hearing, get remarried (equivalent to dying) or loose everything and live homeless in the street... But at least I will be able to set it up for 480V and plug it into a street light transformer and keep my cardboard box warm at night... 🙂
I hope everyone is well. Life is short, smile while you still have teeth! 😀
Transformer placement
Hi,
I will use two 500VA and two 80VA transformers in the same chassis seperated by 70mm (2.75").
Will there be interference between the transformers?
Should I mount them at 90 degrees to each other as is done with inductors?
Thanks.

Hi Harry,
you can mount your mains transformers next to each other without any location problems.

Sometimes they mount 2 trafo's on top of each other....
But not so good for their temperature i think.

Mine are two 700VA one on top of the other. No problems with heat either. They are so heavy you kind of feel that the bottom one is getting smushed but once you are over that its all good.

Hi Lgreen,
with the lower transformer being so squashed, don't you find that the bass/mid range seems come out in sympathy?

Re: xfos
No but the bottome one/left channel sounds more compressed.
haha, just kidding!

Guy thanks for the replies (and humour) 😀
For those who have built their amps with +/-42 volt supplies.
Did you change any of the resistor values/ wattage?
Thanks

Harry, stock works fine. For one of my early prototypes I did increase a few values, but I really abused those test articles.

My unloaded rails were right at 41.5 to 42 volts DC depending on the wall AC (800VA Avel monoblocks)
Loaded down by the circuit (untouched) I'm at 39.6 DC at 400ma bias at 118 volt's AC
The CL 60 (inrush 10 ohm) will reduce your wall AC by almost 1 volt by itself
No issues at these rail voltages

Hi,
I would recommend you use a timed relay to short out the thermistor as soon as stable input conditions have been achieved.
Aim for 500mS to 1second delay.

Good idea, there are many examples of people here who did this in many different ways. Anyway, here is the way I did it, the Power Supply Wiring and Soft Start circuit (green board in the 1st diagram). Shorts out the thermisters with a variable delay and has variable voltage (pick whatever relay you want).
