The EICO 2050 is an excellent amp. It is the sister to the EICO st40, but with less doo dads. The tubes , if they are all stock, are probably Mullards except the power tubes and are worth at least 200 bucks. the power tubes if they are Westinghouse are superior to any others and should be tested to check their strength. Also, be sure to check to make sure your power supply caps are not becoming really hot after short use as this would indicate that they are starting to go bad and may blow up on you.
Re. the record player, any turntable that has the stack the records up spindle is not goiing to be very "hi fi" as the needle and tonearm can be hard on your vinyl. It is probably not a good idea to use it on your collectible or mint lps.
Well, "good eye" finding the amp where you did. You just never know where these things will turn up.
