  2. Here is right review, fully agreed: https://audiokarma.org/forums/index.php?threads/nobsound-fake-hybrid-tube-amp.706645/ i just picked up my amp from my friend, a talented and careful tech who's done much work for me before. indeed, i had gotten the hum in my left channel by accidentally touching a strand of speaker wire across the outputs. while fixing things up, he discovered that the amp is simply a solid state amp with signal running through the tubes in the preamp first, but with no real contribution from that stage. yes, he says, the amp wont play with no tubes in circuit, but that is because they are really nothing more than attractive fuses. he went on to say that overall, it is nicely constructed, sounds good, but is inaccurately called a 'tube amp'. so now i have a $325, $150 solid state amp i don't really need, with tubes lit up on top. I removed the tubes joining the tubes circuit with capacitance 4uF.
  3. My second hand 222 has TR601/602 2SC369 transistors, not 2SC871. Transistors TR801/802 are 2SC281, not 2SC871 as should be. Not sure either it Sansui mod or someone else. Sound is good but too much background noise. I noticed that the noise getting much louder and unbearable if you bring the amp close to a steel table. I cannot understand how the table may effect to the amp. I plan to replace all 2SC871's with BC550C. Maybe it help.

  8. Item: Infinity Primus PS-8 Subwoofer Location: 3183 Price: 180 ono Item Condition: good Reason for selling: upgraded to bigger one Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Great sound and, besides a small dent in the speaker cone, great condition. Infinity PS-8 Subwoofer Features and Specs Enclosure Bass Reflex Video Shielded No Woofer Size (inches) 8 Woofer Composition M.M.D. Firing Direction Front Wireless No Preamp-Level Inputs 3 Speaker-Level Inputs Yes Speaker-Level Outputs No Low-Pass Crossover Freq 50-150 Hz High-Pass Crossover Freq None Phase Switch Yes Amplifier Output (watts) 100 Frequency Response 35-150 Hz DIMENSIONS & WEIGHT Width 10.6 in Depth 16.8 in Height 17.5 in Weight 33.07 lbs Features Metal Matrix Diaphragm (M.M.D.): Derived from the C.M.M.D. material used in Infinity's flagship Prelude drivers, M.M.D. features a stiff aluminum core that provides exceptional strength and rigidity for clean, realistic low-frequency tones. Amplifier: The 8" M.M.D. front-firing cone woofer is powered by a 100-watt (RMS) amplifier. Surround: For a smoother response and improved durability, the woofer uses a rubber surround. Bass Ports: There are two rear-firing bass ports that allow deep bass with high acoustic efficiency and low distortion. Gain Control: The subwoofer has a rotary control on the rear panel for adjusting the level of the bass. Phase Switch: The subwoofer's phase switch allows you to control the phase of the subwoofer's output relative to the front speakers. If the bass sounds muddy or unclear, toggling the phase control can sometimes strengthen the bass "attack." Auto On/Off Circuit: The auto on/off circuit turns the power amp on when a signal is sensed and turns the amplifier off and into standby mode approximately 10 minutes after a signal is no longer received. An LED indicator on the rear panel glows green when the amplifier is on and red when the amp is in standby. Low-Pass Crossover: The subwoofer features a continuously variable 50Hz-150Hz low-pass crossover that determines the highest frequency at which the subwoofer reproduces sounds. The crossover has a 24dB/octave slope. Inputs and Outputs Notes Line-level Inputs: The subwoofer has a gold-plated LFE input and gold-plated stereo RCA inputs. If you have a Dolby Digital/DTS receiver or processor with a low-frequency-effects (LFE) output, you should use the LFE input on the subwoofer. If your receiver/processor does not contain a Dolby Digital or DTS processor but has a subwoofer output, you must use the stereo RCA inputs. If the receiver/processor has a mono subwoofer output, a "Y" adapter is recommended to maximize performance. Speaker-level Inputs: The left and right gold-plated 5-way binding posts allow you to connect the subwoofer to a receiver/amplifier using speaker wire.

  10. Can you try another amp or turn table(you can use headphones for easy setup) to localize faulty equipment? The Mode switch can be dirty. Two days ago I had similar problem. I rotated quickly the mode switch for 3 - 5 times. The left channel came back. If it happens again I will open the amp to clean the switch properly.
  11. I meant it is running hotter compare to Sansui, Rotel, Cambrige Audio and so on I have had. My old Luxman LV-105u is getting hotter than 509u. Luxman Class A amps getting even more hotter. This is AB amp. Actually initially I bought 507U but after a couple of days I decided to pay extra to replace it with 509U. Then I was happy.
