i just got a kenwood trio ka 8300 or also known as ka 701 in the US.
i played it and hooked it up on my infinity sm 120. i was surprised that it was not that good sound as i expected. it turned out that i pushed the volume at 12 o'clock. the sound was that not loud enough and the infinity woofers don't bounce a bit. as if it was in a muting set. i did tried my technics amp a S-VU60 on the infinity. they sounded full and loud. i opened the cover. discovering the power transistors are some what different.( i saw some photos of the ka701 in the bare. and i saw the 3pin transistor which was mounted sideways on the heatsink. connected to a small chip plate and wires to the main amp board.). mines is different the transistors is mounted vertically. and reads (TOSHIBA 2SA 1943). is this the original transistors for this kenwood amp?does this affect the sound value and power output of the amp? i have doubts its been replaced?.. can you please help?
cheers.
one thing more.. the last and 4th transistor on the heatsink has different polarity connected while the other 3 has the same. ill post some photos later thanks.
