Do you want to evaluate this after me Jon?

Ah, I wasn't hinting at that although If you don't mind I'll say yes! There's no hurry as I'll probably need to move my OL arm back onto the P3-24.

That's fine Jon. I will collect it next Monday and am going away for a month at the end of the following week so John says its OK for me to hang on to it until End September/Early October.
Let me know and we can sort something out when I'm back. |

I have been using the GSP PSU1-AC for the past week with both my 'new' Acrylic Rega/TT-PSU and directly into a 24v AC RP6-Planar 3 hybrid and
can confirm that it easily powers both at 24v. John C checked it out
for me at 245-252v (something within this range seems to be common in my house) and it
was outputting 25v. Music sounds rock solid with no noticeable wow or flutter, even on sustained piano notes so all is good.
I haven't done any serious back-to-back listening vs the two original wall-worts yet, that will have to wait for a few weeks. |

Picture of the PSU1-24vAC (rear) & Rega TT-PSU with twin turntable switch box (mounted in a PSU1 casing, LH side). A single 4 pin Kycon connector goes to the TT-PSU with twin 4 pin Kycon connectors to the PCB housing on each turntable.
Measured with the Turntabulator app on both platters, the main turntable with a GT reference subplatter reads exactly 33.3rpm, the other with an aftermarket alu subplatter reads 33.4rpm. At 45rpm I get the readings 44.98rpm and 45.01rpm. Pitch is stable on all settings and I have removed two potentially 'noisy' wall-worts, replaced with the linear GSP power supply - also freeing up one wall socket. |

I would be interested to know if this prototype went any further into consideration for development, moreover, is it possible or plausible to have the one PSU1 supplying both the DC required for the Phono pre AND the AC for the Rega? (As you can tell, I know very little about electricity)
I am pretty interested in the options to replace my Rega wall wart for the TTPSU, it has a terrible buzz from the back of my cabinet, and a reputable high quality option to replace it with is on my agenda, as well as a new phono stage. Thanks |
