My Audio System in my hobbit hole

I like listening to old formats: analog records (more than a thousand) and one hundred CDs. Most of composers, players and recording engineers were dead long ago so that my listening style does not contribute to any economic or social  activity.

Equipment Model Remarks
CD Player PIONEER PD-10AE  bought in 2019 
Cassette Tape Deck PIONEER CT-970 manufactured in 1981
Record Player BSR/SANYO Rim Drive Motor Kit for 16/33/45/78rpm for playing SP/LP with turn-over ceramic/X'tal cartridges
Full Automatic Linear Tracking  System TECHNICS SL-J2(1984/1985) with T4P cartridge. I picked up others from junk too, but after some time of use, all went ill-functioning so I threw them away. Around 1980 many full-automatic linear-tracking models were produced in Japan and now they are available cheaply from recycle shops. Technics SL-10 jacket-size linear-tracker and a few Yamaha linear-tracking models are still highly appreciated by audio-maniacs as monuments. IMO: There is no essential merit of low lateral tracking angle error +/- 0.15 degree while the demerit of linear-tracker is uncountable in practice: unstable mechanically. Another demerit of jacket size turntable: it cannot use record weight/stabilizer for warped record because of space.
SL-J2 with quartz-lock has rather complicated system with band detective sensor beside plug-in cartridge P-30. When this stylus is worn, I have no plan to buy expensive replacement stylus any more.
Linear-trackers require regular maintenance generally for arm system: 
   ①change of drive belt for inching arm 
   ②change of grease around worm/pinion gear
   ③cleaning of rail
In fact, slide friction on linear trackers is higher than rotational friction of pivotted swing arm. To keep slide friction low and steady is difficult: not maintenance-free.
 recycled from junk in 2006. 
Full Automatic Quartz-Lock Turntable System DENON DP-7F (around 1987) : swing arm with T4P type cartridge DL-7F
Now I am using this model as manual player for more than 15 years.
recycled from Junk in 2005
Turntable DENON DP-2000 (around 1977) Quartz-Lock Direct Drive AC Motor - Nude without case and arm.  Running more than 10000 hours: I was used to hear average 2 or 3 records almost everyday during 1978-2000 with this turntable. It works still fine but I play other automatic turntable system for easiness now. Turntable & Arms are placed on  Dupont "Corian" board 
Tone Arms (standing alone) Micro MA-505 (1976) Dynamic balance arm with detachable shell
CEC HA-937 modified to integral arm silicone oil damper
SME 3009 Series II improved (early model) integral arm without fluid bath
Infinity Black Widow  with fluid bath
Keith Monks Laboratory Arm M9BA Mark III, which I assume as most advanced uni-pivoted arm with magnetic anti-skating device & silicone oil damping similar to Decca International Arm Mercury contacts are dangerous but free from wire friction around pivot.
Cartridges ADC XLM II improved, Audio-Technica AT33PTG & AT-MONO3/LP(Monaural)
Denon DL-102(Monaural), DL-103, DL-110 
Dianix Sigma-1000MC by TECDIA  = Clearaudio Sigma (early model)
Dynavector DV-19A 
Excel SS-20, ES-70S, ES-70E, ES-70EX
FR-6SE, Ikeda 9cV
Ortofon SPU Classic G[1987] with tip R17micron, SPU Mono G[1989]with tip R25micron & sticker on the box indicating SPU Mono GM ,  SPU Classic GTE[1994] and MC20S2[1997]   
Pickering 625E-S2, NP-AT plus stylus(D1527) for SP
Shure M44-7, Me97HE
Sony XL-55(Monaural) etc
Plug-in  T4P cartridges Denon DL-7(MM equivalent to Nagaoka C-502M/P because replacement stylus is common) & Technics P-30 with EPS-30ES(elliptic) etc T4P cartridges are interchangeable: VTF 1-1.5g (average 1.25g), weight 6g, 2cm from connector to stylus.
Head Amp for MC Kaneta-type DC Series No.40 battery amp 26db built up in 2002
Step-up  Transformers for MC DENON AU-300LC Input impedance (3-40 Ohm)
PEERLESS SLC-1  Impedance (3 Ohm)

Pri Amp San-ei kit PR-300 (tube) 26.5+20.5db  Ampex-Dynaco circuit
Attenuator Home-built  T type attenuator: input stage with 0dB buffer and output impedance 600Ω constant  (Year 2000) use after Phono Equaliser/CD and connect to power amp directly

Home-built Single Triode Tube Amp (2W x 2) NEC 6C-A10(50C-A10) 1980
Line Amp (20dB) for Headphones Home-built All-FET amp (2002) Headphone: Sony MDR-CD900ST
Speaker Systems KEF Q10 (only one channel for use of SP playback) Uni-Q unit (1998)
Full-range LC-12S (5 inch) for music of old sources.
IMO: Wide frequency equipment is unsuitable for old recordings which sound unfocused or strange with wide freuency speakers. Frequency range is limited to 80Hz-10kHz +/-3dB, but it sounds real and focused for old monophonic source and vocal.
Box from Hino Audio in Akihabara who produced copy models of Goodmans Maxim system.
Two-ways bass reflex type speaker system.  Unused for the moment. Hino Audio in the same box as above.
Fostex FF165WK (6.5inch) plus drone-cone (8inch Fostex Woofer FW20 as dummy cone) to enhance bass range. General use including symphonic music.  see drawing
