Note that this is only for 120V input.
I did order the Connex SMPS300REh PS directly from Connex for 230V system and specified +-24V. The REh medel has an aluminium base plate that transfers the heat from rectifiers to whatever it is mounted on. Works really well with my F6, barely warm base plate.
I have the dual version of PO89ZB-like (have another name I cant remember) filter in front of a bank of caps.

Is there a ACA mini build guide, or one in the works? I saw the photos in the ACA Mini thread, but this is my first solid state power amp build and I'm a little concerned about, among other things, correctly making the transistor/heat sink interface. USPS says my deliver is coming today, so I'll be putting aside some weekend time for building fun! Thanks in advance - love diyAudio and especially the Pass connection to it!

Am building the Nutube preamp with the complete kit. Step 42 - testing the power supply, I got almost 24volts. But at the diode, I am getting only about 8.95 volts? I did this check before adding all the other components. Anything I should correct? The instructions did not say what to do if I don't get 9.5v.
Thanks in advance, I appreciate the help.

This request for help may remind you of an episode from "Car Talk" - the old PBS show, but here goes.... I completed the Nutube preamp, hooked it up and am getting very good clear sound from the left speaker only. The right speaker has a low volume sound like a motor running but no music. Would appreciate any help and advice. Thanks

If I switch the output jacks, the music switches to the other speaker; if I use either input - the problem remains the same. Both lights on the Nutube are on; Checked all the external wiring vs. the build guide. 🙁
Exacly like that.
P.S. Beware that this supply does not like large caps efter the regulated output.

This is an awesome thread.
I’m new here, pardon the disturbance but I’m interested in replacing/upgrading capacitors and other aged parts in an Adcom GFA 5800. I like everything about it currently but just wondering if higher quality caps, etc would help it shine even more when playing my Mirage M3si (83db efficiency) at concert volumes.
