    Sensitivity and "hard to drive" speakers

    Glad the OP posted this question as I,ve had the same question in mind. I do understand that some amps cannot dip down into that 1 ohm range without issues , but I am wondering what does a speaker gain in audio quality by demanding that much power at say , 20 khz? as compared to a speaker that...

    Lintons vs NLAs

    I,m just curious if anyone has updated from the New Large Advents to the Wharfdale Lintons. If you have , what were your thoughts? I,ve had a nice set of the NLAs in my main set up for quite a few years and have always enjoyed them. However , as always , I,m getting the " upgrade " bug and have...

    What Record Are You Hearing Now?

    Its been remastered by Kevin Gray and pressed on 180 gram vinyl and limited to 5000 copies. This is the first one of the new series that I,ve heard and I think he did a great job. I,m definitely not an expert but I can safely say my original copy of this album wasnt this clear and dynamic. Not...

    Pioneer phono pre amp thoughts..

    Pyrrho....thank you for the input and your thoughts. I,ll probably move on do a little in depth research on stepping up to a higher end turntable. The SX850 does have a nice phono preamp and as you said , there are other areas that an upgrade will affect more. I,ve been recently into some of the...

    Is Home Theater On Its Way Out?

    interesting subject..... looking at it from my perspective , I have a nice mid level HT setup which I,ve had for a few years now. Early on we did use it extensively and really enjoyed sitting down and being immersed in a great movie with some amazing audio to add to the experience. However in...

    Pioneer phono pre amp thoughts..

    I recapped and replaced most problematic transistors on the 850 a few years ago and have always been impressed with sound quality , either through the phono stage or any other inputs I use ( mostly bluetooth and a TEAC A 2300s I also redid at the same time. I also have numerous amp and receivers...

    Pioneer phono pre amp thoughts..

    I,m just curious as to what everyones opinions are concerning the Phono stages in their vintage recievers. My main system consists of an SX 850 , Dual 606cs turntable, RG9 dynamic expander and NLA Advents. I have no issues with the sound quality and no complaints but , as with most vintage audio...

    SX-850 Adventure

    good luck on getting the 850 up and running! I bought an 850 a few years back and it was my introduction to working on vintage equipment....hadnt even picked up a soldering iron in almost 40yrs. The 850 had numerous issues starting with the " no relay click" to distortion in the phono section...

    question regarding replacing a lug style cap with a radial style on a main power board.

    Painted, thanks for the follow up. The 6800/50 radials I have are newer Nichicons . Can I jump up to 8200uf without any issues? I know its the power supply and shouldnt affect sound, but wasnt sure if anything else would be affected. I,m always going up , voltage wise , when recapping but dont...

    question regarding replacing a lug style cap with a radial style on a main power board.

    Is it considered acceptable to replace a lug style cap on a main power board with a radial cap? My Pioneer SA 6500 Mk2 has 2 6800uf caps ( 42v) with lug spacing at 22mm. I dont see any replacements available on Mouser or Digikey that come close to those lug measurements. I do have 2 6800 uf 50...

    Low level phono hum SA-6500II Pioneer

    Thanks Mb.... I,ll give that a shot. If I didnt know better I would assume it was a grounding issue. After replacing the caps , I hooked up a pair of speakers and the hum was still there. I was going to carefully jostle a few ground wires to see if anything would be affected and every time I...

    Knob for SX-3700

    Those parts do pop up on Ebay now and then. I picked up a 3700 recently that had seen better days. I did find 2 replacement selector switches ( 2 were missing) and was able to repair 2 other selector switches that were broken. The only part I cannot find is the light bulb holder for the 4 lights...

    Thanks for the help , not sure on the KSC1845YTA.... it may have been a mistype by the OP. The TA makes sense as they are delivered on a strip of tape. Thanks again!

    transistor question...

    The ones I have from Mouser are labeled " KSC1845FTA " on the package and the transistors themselves are stamped " C1845FCJ20 " ( at least thats what I can make out on them as the writing is very small! ) Mouser part # is 512-KSC1845FTA. The KSC 1845 YTA was recommended as a replacement...

    Does anyone know if there is a difference between a KSC 1845YTA transistor and a KSC 1845 FTA transistor ? I want to replace a few old 2SC 458 transistors in a Realistic receiver and according to the forums , the replacement for these is the KSC 1845 YTA. I have the FTAs on the shelf . Are they...
