Lite Audio GA-31a phono preamp, is it a clone?


Hello everyone,
I recently purchased a Lite Audio GA-31a phono preamp. It should be a clone of an authoritative but probably old project. Does anyone know him? Can you tell me which product?
And what do you think of it?
Thanks

Hello tablejockey,
I bought it in Italy. It is used but assembled with great care and at a low price. I'll get it next week. Currently it mounts 4 6922 Electra Harmonix tubes but I intend to replace them with 4 Philips 6922 nos valves or with 4 Amperex 6DJ8 orange logo.

It's an unusual circuit in that the tubes are used in what looks like a cascode configuration with transistors doing the amplification. Are the tubes there to add gain or flavor only? There's also a 47uF electrolytic cap on the single-ended input which is not good.
I would give the stock tubes a chance, before putting costly NOS tubes. Also, there may be just one slot where rolling tubes makes a noticeable difference.
Hello noromance,
I had already noticed this hybrid setup. I hope it is a wit to improve the project, not a defect.
About the 47uF electrolytic cap on the single-ended input, what do you recommend to do? Remove it? Replace it?
Tenx!
