bitece Posted June 12, 2005 Share Posted June 12, 2005 I recently purchased a Soundcraftsmen model 5050 amp/preamp from Ebay. The amp work's wonderful when using the Aux input but when I hooked up my turntable I noticed that I wasn't getting any low frequency from the output. I connected the turntable to another amp and it was fine. Any ideas on what the problem may be? The output from the amp was definitely compromised.

boom3 Posted June 12, 2005 Share Posted June 12, 2005 Sounds like the RIAA equalization is off, from, perhaps a bad component and/or the wrong setting. I'm not familar with that model, does it have more than one phono equalization setting, as the preamps of the early 50s did? Quote Link to comment Share on other sites More sharing options...
bitece Posted June 12, 2005 Author Share Posted June 12, 2005 No, there aren't different settings for the phono. I connected it to the mag inputs. Quote Link to comment Share on other sites More sharing options...
dewickt Posted June 12, 2005 Share Posted June 12, 2005 The last Soundcraftsman I had on the bench needed a complete recapping, it used the bumblebee caps thruout and half of them had significant leakage. I suspect what you are hearing in the phono section are bad capacitors or a phono input that is set up for a crystal cartridge that does not use RIAA compensation.
