My small monoral system
Here I would like to show my monral system. I use this system for reproduce monoral records.
　

For the pickup, I chose General Electric RPX 050. The RPX can reproduce both SP and microgroove records to exchange the stylus. The styluses of the RPX can still sold via stylus supplier, although it is a reproduced one. The tonearm is made by Yamaha in 1960's. These combinations fit to the old records.

Monoral equalizer amp BASIC-NT

Monoral equalizer amplifier "BASIC-NT" (2003)

 I built small monoral equalizer amp based on Westrex RA1474A mic amplifier. 600 ohm Output transformer and T-attenuator are installed in the case. I used proper VU meter made by Yamaki electoric, Japan, but the outer casing has exchanged from an older meter.




　
The power amp using was WE101M-WE205D single amplifier. Although glass suport of the 205D is broken, it works fine. But to consider the condition, I switch on this amp only to hear the system.
　I built this amp when I lived in a small apartment. I remember that old days when I use this amp.

PA speaker

Telefunken PA speaker box (1951)

 This speaker box was made by Telefunken, and I guess this speaker was used for PA system in a room or a cabin in train. However, the sound, especially human voice is very realistic.
