Post Subject: Oh wow!Posted by N-set on: 12/16/2019
Just incorporated this wonder into my system! haven't heard a live orchestra broadcast yet but even voices from the studio have something special, some magic aura.
This is how I use it:
- cleaned (down to dismantling all the switches) and calibrated by the local service specialist
- he didn't feel to bypass the FA7 board completely but he soldered a bridge across the switch (previously cleaning it)
- I use outside 75R antenna, I installed on the roof - simple 167cm straight one; the radio emitter I'm interested in is about 3km straight line with almost no high buildings in between although all is in the city center.
- the signal I was receiving wasn't very strong at about 60dB (other stations were shooting up to 80dB) but in the stereo mode there was an audible distortion
- having read this thread (thanks Romy!) I installed 20dB antenna attenuator. Bingo! The noise was gone with a beautiful, full sound. I'd try even more attenuation but cannot find RF attenuators above 20dB. Anyone any ideas?
- the tuner has its original crappy 2 prong cable. I grounded it using the GND connector at the back (my amp is not grounded so this is the only grounding point and I prefer to have it)
- I've discovered a SHOCKING fact - Edison-type decorative bulbs emit RF rubbish 
Hard vacuum, filament bulbs! I could hear a gentle RF interference when they were on. This was my listening light...I change them now to modern incadescent bulbs. Here is some great info: https://www.radiomuseum.org/forum/rustika_lightbulb_fm_measurements.html
Any other advices on how to get max out of this baby (without going into to much mods like described above)?
Cheers,
Jarek
