Just acquired a beautiful-condition Sherwood SEL-300 tuner and SEL-400 integrated amp. While the tuner is fine, the 400 powers up without turning it on! Checked with headphones, and all you get is static and a faint signal through all incoming channels - and a loud hum. Have not and will not test with speakers until issue addressed. The unit appears to have not been tampered with, fixed, etc. I'm no expert, but no dummy with vintage gear, either, and have never seen this problem before. Anyone have any insight?

this should be a 1960 bass and there was 18,000 of them made so it is not rare but the questions that must be asked to put it in the rare category is the bass 100% original = this means everything /pots /pickups /tuners /frets /finish and then the overall functioning of the parts EX. bent tuner that turns restricted causing tuning problems / pots that cut out / input jack that's screwed up / buzzing or severely worn frets /and or fret board wear /worn finish on the body/neck so you must go down the list of everything to come to the overall condition of your bass then you can grade it by it's condition and then see where the basses category is (PRISTINE) =never used still tags & case (fine) = slightly used tags & case (excellent)= used but no finish chips scratches everything original & working so you get the picture I am curious about this because most players know there basses very well so this tells me that you have acquired this bass recently or that it belonged to a family member? and was passed down to you post back with more info/pictures of the bass I'd like to see it Stephen
Turn the radio on and press the Set button. When the "P" displays, press the Sel button. Use the tuner dial to set hour.then press the sel button again and use the tuner dial again to set the minutes. Press the sel button once more and the time is saved.good luck
You seem to be looking for an amp made for car audio. There are many brands, but I going to give you the specs for your particular speaker which will help in choosing, not a specific name brand amp, but at least one with the proper power outputs/requirements.
Your speaker, based on the model number you provided, is rated at 4 ohms .Power handling range is 50-300 watts. And a peak of 600watts. That does not mean start cranking 600watts thru the speaker, it will blow. I suggest you acquire a single (mono) channel amp that provides 350-400 watts at 4 ohms.
Check the speaker wiring in the back. Make sure it is not wired improperly.
You could remove the speaker wiring from the back of the amp and see if it still shuts off after turning it on.
If it still shuts off after the wiring is removed, it is a problem with the amp itself.
If it remains on after the wiring is removed, then I'd say you have a problem with the speaker wiring or the speakers themselves. It still could be a problem with the amp in this case though... just a problem when it is trying to put power to the speakers.
I am having the exact same problem with my vauxhall corsa and my pioneer deh-6000ub its so annoying it works with the manufacture stereo soon as i connect my pioneer in it doesn't come alive (the HCB-400)
