For the use of CL-60, if I were to have 2 CL-60 wired within the primaries of the AN-6225, do I still need to have a 3rd CL-60 connected to the chassis and ground as what Papa Nelson recommends?
Further increasing capacitor values
Thanks a lot 6L6 for all the build guides, they are incredibly helpful!
Quick question on capacitor choice, I am tempted to go for even higher capacitor ratings for my F5 build, I have seen this on Digikey, almost 3x higher capacitor rating compared to original specs.

Is there watch out that I need to be aware of?
I am planning the rest of the power supply as; CL60 thermistors as described in the datasheet, 400 VA transformer (2x18 V) and 2 monolithic bridges (GBPC3502)

Hi Guys, I'm building the F5T v2, I'm using a 1000VA 24v+24v transformer. I'm trying to source some PSU Caps, they seem to be sold out from most suppliers. I did fine these Rubycon USC series caps 22,000uF 50v, what are your thoughts?

with 18,000uf caps (647-LLS1H183MELC) in an f6 universal psu, will I be blowing fuses on start up w/o a soft start?
Also I see 2000 and 3000 hour lifespan ratings, and some with no life span rating, should those w/o a life span rating be avoided?
I am trying to go for large 35mm dia x 45 mm or 50 mm hieght, worth the effort?
Most are 35 x 35.

You can't buy those caps... they are out of stock! 😀 Here's a good one with 1000+ in stock SLPX183M050H9P3 Cornell Dubilier - CDE | Mouser
Really though, they or similar will work great.
Don't overthink the caps - 10mm snap-in, 35mm diameter, 15,000uF or bigger, 25V or higher.

I agree @6L6,
I ended up with these Nichicon 35v 22,000uF 105Deg for my F5T. 175 pcs left in stock.

Thanks for the quick replies fellas, and especially the part number / link, that makes life much easier. I'm new to this, so looking up parts can be tedious, and sometimes confounding! Ordering those tonight, the price isn't bad either.
If your transformer is rated anything above 250-300VA, it sure will...try using CL60 thermistor in series with live...you will be all good
Ordered rectifiers for psu, both Mouser and Digikey show FEP30dp-e3/45 as out of stock, after sniffing around I ordered these 625-FEP30CP-E3.The only difference I see is Vr-Reverse Voltage is down to 150v from 200v, hopefully still adequate. Enough for tonight, my eyes have glazed over.
6L6, my Pop is / was an electrical engineer, mentioned on the phone what I ordered and he said "oh yeah, "double - ear" is a good outfit, that's what we always called them anyway". Got a chuckle out of that.
Few helps for Danilo (newbie)
Hello from Danilo (first post, newbie, Italy, Rome).
I've few questions... maybe someone want help me?
1) I would like to buy the Antek AS-4218 Transformer; how to get 18V from input AC =230V (and not 115V) ?? Is it sufficient following the 240V section of the attached schema?
2) I don't understand how to choose the capacity: In the web I can find both 10-15.000 uF and 33000 uF. How the output depends upon the capacity?
Thanks a LOT!!
Danilo

Man, Went through all these post. I'm Building a sneaky Pete M2 Clone amp in a Denon enclosure. I've seen two different grounding schemes. First: has all grounds connecting to the star ground on the PSU board including ground from the transformer on the Chassis. Second: Two different grounding points. IEC Ground to Chassis and Star on PSU everything else. Any preferences? Also I have an Antek AS-3218 transformer so ground (Purple Wire) always goes to the Star PSU ground on either Configuration? Cheers
Purple goes directly to the chassis. Same place the safety earth from the wall attaches. Do not connect to audio ground.
Starground on the PSU works pretty well, but the PSU ground should be elevated off the chassis by a CL-60 or a couple big diodes. CL-60 is easiest.
Check your PM

Got it! Makes sense. Thanks! Just waiting on some bypass Caps for the full build. Dude, You are really close. Stonegate!

Question regarding the resistors on the PSU Board. R5-R8; it looks like the flow goes from the bleeder resistor (R9), to the LED, the resistor to the LED to R8 down to R5. Due to space constraints I only want to use the space for R6 for an Inductor. Can I jumper R8 and R7 so the circuit completes to R6 where the inductor will take over?
