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) Quartz Direct Drive with T4P cartridge (stylus EPS-30ES)
and optical sensor beside cartridge. I salvaged several linear trackers 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. 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 As usual there were variations such as SL-J1 (1984) belt drive with stylus EPS-30CS, SL-J11 (1985) belt drive without skip function (ecomomy model of SL-J1), SL-J3 (1986) Quartz DD with stylus EPS-30ES and 8 push switches to select program or band. |
| Full Automatic Quartz-Lock Turntable System | DENON DP-7F
(around 1987) : swing arm with T4P type cartridge DL-7F (stylus DSN-67) Now I am using this model as manual player with auto-return function 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 automatic turntable system for easiness now. | Turntable & Arms are placed on Dupont "Corian" board |

| 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. | |

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. Some old movie music and songs by Andy Williams etc. were recorded with too much echo/reverb: it was designed for the limited range of reproducer (radio or movie equipment) and not for current Hi-Fi equipment. |
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. This type using drone cone is now almost obsolete, but it has similar effect as enlarging the volume of tight box. | see drawing |
