  1. New ad with some new photos of internals. https://buffalo.craigslist.org/ele/d/getzville-sony-ta-90es-preamp-and-amp/6859569317.html Thanks, Serge
  2. Thanks JBCODD, I'll make more pics in the next couple of days. Maybe will pull the cover off and do few of internals. $1200 for both pieces. This tbh is discounted compared to what they go for on interwebs, but I would consider further discount for folks on this site. I can only do local sale though. These are too heavy for me to pack and lug them to post office. Serge
  3. Hi, I have not visited this forum in a long time, so moderators, if this post is violating forum rules, please remove it. I have Sony TA-E90ES preamp with working remote and TA-N90ES amp for sale on Craigslist in Buffalo area. Here's the link: https://buffalo.craigslist.org/ele/d/getzville-sony-ta-90es-preamp-and-amp/6859569317.html Thanks, Serge

  5. Hi Josh. How does your new Benchmark perform at low volume? Is there anything lost at low volume when compared to your normal listening level? Have you tried different gain settings? What’s your preamp, other than Benchmark DAC? Thanks Serge I have used the Benchmark DAC as the preamp using the George Wright Phono stage . I have also used My Juicy Music Merlin preamp using the George Wright Phono. I prefer using the Merlin but the Dac on its own is pretty remarkable . The Benchmark has three input gain settings. I can switch betweent he three and find the quality that pleases. I cannot tell you what the gain numbers are - Im sure they are on the Benchmark Website. The manual says to use one with pro audio and one of the others for other preamps. Its pretty easy to hear and find the input that works best with your preamp. The Amp continues to amaze. It is truly another world! Josh Thanks Josh. How's Benchmark's low volume performance? Is much lost when compared to normal levels.

  7. Interesting amp from a sister company of MC2 Audio. Has the network DAC, DSP, and web remote: Serge
  8. I think this was due to Klipsch re-using the Forte boards for early Forte II's. No other way for them to adhere to the schematics, but to reverse the highs and the mids. This all is just my guess though.
  9. I think I got it. Ordinarily, the polarity reversal would be taken care of within the network and “+” at the board would still go to “+” of the driver, even if the actual polarity is reversed (is this assumption correct?). My Forte II’s are from 1990 and still have boards marked “Forte” and show reversed mids and highs clearly marked at the board’s terminals. According to schematics, Forte’s have only mids reversed(within the network) and highs not reversed and I assume show pluses at the board going to pluses of the drivers for all drivers(would be great if anyone could verify this). The corrected Forte II diagram above shows the highs reversed and mids not reversed. When re-using the old Forte’s board, Klipsch could only take care of the reversal either at the board’s terminals or at drivers terminals, but not within the network itself. My tweeters do have terminals clearly marked and pos of the driver is connected to neg marking at the board. All this leads me to believe that my mid’s negative at the board(again clearly marked) is connected to positive of the midrange driver(which for some reason is marked with random character “R”). Does this make sense? Yes..........this is what I was suggesting. Something else...........I am also suggesting that the white mark is not an "R" at all. It's nothing more than a squiggle to mark the positive terminal of the driver. I'm guessing. I have drivers with marks on the positive termiansl that just look like squiggles. Klipsch also marked the speaker wire terminals on older models. I have a pair of 1973 vertical conrwalls and the speaker terminals have red squiggles on them to mark the positives. Mark, you were right. Reversing polarity at the drivers didn't make sense. What threw me off originally is that both highs and mids on mine are reversed at the board which didn't correspond to the Forte II schematics.

  11. As mentioned earlier, the Forte II network has the polarity reversed on the squaker. This might be why they indicated with white and with an R. The R indicates connect the red wire here even though it is actually the negative terminal. If they would have used '+' or a red dot, then a person without the schematic or the ability to read it, might connect the driver backwards. A white 'R' is the perfect answer. I speculate 'R' = negative, and it is where you will connect the POSITIVE wire. It looks to me like there is a '-' (minus sign) in the plastic where the left part of the 'R' is. That would confirm my hypothesis. edit: The Forte schematic shows the reverse polarity correctly. The Forte II schematic shows a dead short on the left of the 1.5uF cap. This is a misprint, I am sure. The feeder to that cap should come from the positive wire and end. The positive and negative wires should not be shorted together after that. See diagram notes: If R is negative, than mids connect from reversed at the board to negative on the driver which would mean polarity is not reversed. What looks like the '-'(minus sign) is metal terminal reflecting in the plastic.
  12. Thanks. I've been thinking about exactly this for the past few days. Pity. My drivers are in great condition.
  13. Thanks Mark. Bob's site reports different marking from the one I have. It's yellow dot. I tend to agree that wires are reversed on the PC board only. If so, looking at the marking on the board I have both highs and mids reversed.
  14. Thanks Arash. This is a great test, but I am not sure if I can perform it with this diaphragm. I am reluctant to attach anything to the windings.
