JIMMY's Tube Audio System
Last Update: July 30, 2006 at 08:44:06 IP Address:
Amplifier: Modified pair of 1946 Hammond Jensen model G monoblock amps with four PP triode connected 6V6s, Raytheon USA 6CG7 phase splitter and MQ iron. The power supplies are a LCLC to 6V6s & another LC at the 6CG7 with a plate choke. Rectifiers are Sylvania 5R4G. I use Russian K40Y-09 coupling caps- excellent.
Preamplifier (or None if Integrated): DIY Tung Sol 6P5GT line stage with Mullard EZ81 rectifier. Power supply is LCLC to two seperate LC sections plus plate chokes. Such a simple design here. Superior to Bruces GG design per my ears.
Speakers: DIY 2.5 way speakers with Seas T25CF001 Excel, Peerless 8" HDS Exclusive & 12" Pioneer A30IR50-51F. Ported 2.7 cu ft with a sealed .5 cu ft inside for the Peerless midrange to reduce low frequency response. System has a first order series crossover for the midrange & tweeter plus a simple first order crossover for the woofer. Crossover is 125Hz & 2kHz. The front panel is tilted about 15 degrees for superior time alignment. The Pioneer woofer is much better than the name implies & was not a cost cutting measure. Simply a tube amp friendly & dynamic speaker system that sounds like a live performance.
CD Player/DAC: Modified Toshiba 3950 with 'Vinney' mods & AuriCap direct off of the D/A converter- not a good sounding CDP thus sent to the DVD room.

Pioneer DV-333 with mods- far better CDP.

Turntable/Phono Stage: None.
Other Source(s): Eico Classic 2200 tube type FM tuner with some mods plus tube rolling for superior sonics. Best FM tuner I ever heard to date, may be the best stereo type available after mods with sonics of mid quality CDs on best FM stations. I believe I am the only person at AA that owns a 2200 Classic tuner.
Other Accessories/Room/Misc.:
Speaker Cables/Interconnects: 10 guage zip cord. Old 1950s Hammond interconnects- better than some more expensive cables- go figure.
Other (Power Conditioner, Racks etc.): Tripp-Lite line conditioner/regulator- simple & works.
Tweaks: None
Room Size (LxWxH): 19 x 14 x 8
Room Comments/Treatments: None.
Music Preferences and Comments:
Music Used (Genre/Selections): Most music except Rap & Opera. I like Jazz & Classical music for easy listening. '70s thru '80s Rock is an alternate with the right mood.
System Goals/Comments: I need a better CDP & perhaps a turntable in the future. Waiting on newer technology.
System Strengths: Large 3-D soundstage with lots of air and 'black' in-between instruments and voices. System is detailed without any smearing, grain or sibilance on voices. Finally, the audio is close to a live performance on best quality CDs after 10-12 previous amplifiers (I lost count).

System Weaknesses: Could be more dynamic sounding.
Video/HT System: Integrated
TV/Projector: Philips 27 inch CRT.
Processor/Receiver/Amplifiers: Denon AVR 87. One of the last Denon HT systems assembled in Japan, later models were from China.
Speakers (Center, Surrounds, Sub): Speakers are DIY old experiments.
Sources (DVD/VCR): Toshiba 3950 (audio experiment) dedicated to DVD only use due to poor music playback.
Other HT Gear: None.
Comments on HT System: Ok for movies, solid-state unit is just terrible for music playback. The Denon best feature is reliability.
