I 've recently bought this vintage amp, together with the matching tuner, to play records in my garage/workshop. I bought the set out of nostalgia, the VU meters look so cool. But hooking it up I am truly amazed about the sound !

For starters it goes loud for being only 35 watts/channel ! I don't need tone controll at all, the unit has this natural beefy sound. It's hooked up to a Wharfedale passive subwoofer which is connected to two decent satellites and the sound is simply amazing.
Every switch and controll works trouble free. Even cosmetic it's in mint condition. It's true, they don't build it like that anymore...

Never expected this from this set. I play my old records over it on a Philips direct drive turntable and I am happy as a kid !

Conclusion: if you see this amp passing by, it's worth your money. Cheers, Ludo

very good system would highly recommend it,. as it being an older series i still find them the best, work great and sound really good, out of the past couple I've had this one really is the best tho seemingly hard to find,.



re: SU-Z2

hello guys,

one of the two electroluminescent diodes does not work anymore. Could you tell me what kind of diodes these are and if it is possible to get some new diodes?

Thank you very much. I really like this amp. The sound is warm and I very like its design.

re: SU-Z2

Did you get an answer to your question? Because one of my lights gave up as well ;)

Kind regards!

re: SU-Z2

no apperently not. i think it is not possible to get the original lights though. i just bought a slightly different light.it differs in size but it works perfectly. the new bought light is a little bit thicker and it does not fit exactly onto the appliance. so it is a little bit tricky to install the light but it is manageable :-) .

i bought this kind of light:

Pilotlampe 8V, 150mA (0.15A), 6 x 30 mm

in german its called pilotlampe. i do not know the proper english name but i am sure you'll find something.

i hope i could have been of help. good luck with your SU-Z2. I really like that amp
