great to hear, glad you're enjoying the PH20, thank you!

looking really good, nice job on the wiring. How are you liking the updated PH20 phono preamp? I've been using FPE for over a decade now, they are very good, great quality!

have just released the balanced XLR in and output version of our very popular model Aretha MKII 6SL7 tone control preamp. These are true balanced in and outputs, using the excellent INA2134 and THAT1646 chips to do the balanced to unbalanced and vice versa conversion. We can build any...

We have released the second version of our Titan series tape head preamp, Titan III. Titan III is an all tube preamp, 4x E88CC/6922 tubes, with transistor CCS. Our Titan II is still the hybrid version, JFET/MOSFET input stage and E88CC output/buffer stage. The circuit of Titan III is very...

good to hear that our loudness kit is working well. I use the loudness a lot with my listening sessions, as I do tone controls.

just the listing you see on the above referenced sales page.

We are pleased to announce the release of our high end headphone amp, model Tethys. This is a gem of a headphone amp, an extremely 'simple' circuit, only two tubes, 6922/E88CC and a very 'complex' regulated power supply to ensure total noise free performance. All transformers are the excellent...

just goes to show...paying big $ for audio gear does not at all guarantee one will get big $ worth of gear....yes, over priced audio gear is a pet hate of mine...:crazy:

Titan MKII is quite an improvement over model Nina. The preamp circuit itself has not changed that much, the biggest change is the power supply which is a completely new design. The playback EQ is also a new addition, as are the calibrated VU meters.

OK, I have just updated the PAS upgrade kits web pages and added the pcb dimensions. This should make it easy for anyone wishing to use the PAS upgrade kits for their own non PAS stand alone tube phono or line, or both, preamp.

that does not really matter in having supplies not used. Even if I were to re design it and still using the on board transformers, the size would not be any smaller, as it would still need the regulated 24VDC filament and regulated B+ supplies.

don't know, never thought about that. But would be an interesting thing to look into! I will update the PAS upgrade kit web pages and add pcb dimensions, so that this kind of thing would be easier to figure out.

yes, in fact, most of our PAS upgrade kits can easily be used for stand alone or non PAS builds. The power supply you have used, our regulated power supplies, https://www.erhard-audio.com/Power-Supply-Kits.html, kit#7 or kit#8 is perfect for it, fully 'self contained' with the power transformers...
