Heh, here in the Vancouver radio corridor, the dial is jammed with tweeny-pop and classic rock or 24/7 news and traffic. Why I stream WBGO Jazz from New Jersey or KKJZ from Long Beach, California... which have decent bit rates :-\

Do you know their bit rates?

No, unfortunately. The version of VLC I use doesn't say. KKJZ uses an AAC codec while WBGO uses mp3 is all I know.

Hi, with the assistance in the form of schematics scanned for me by phahn, the tuner is performing much better. It seems that Radio Shack made several quite similar tuners. At least three kits and one assembled version. All were variations of some Harmon Kardon ones that were contemporary with it. Mine seems to be a slightly different kit version than the one in the scanned schematics. It has a few different components and is missing some that were mentioned in the alignment procedures. No real problem with my shop full of test gear. Since the layout was the same and the major components were as well it was serviceable.

One thing was of interest to diyers working on vintage gear though. The tuner has a non-polarized two wire AC mains cord. Internally to the amp is a 0.05uf capacitor attached between the chassis (which is ground for everything in it as well as the antenna and output jacks) and one side of the AC line. When I hooked it up one way in my shop (everything is three wire IEC connected) it tripped the ground fault protection. Turning the plug around was OK. The biggest problem can occur if you hook up sensitive test gear to the unit when it is operating. The initial voltage spike can easily cause damage to the test gear. I killed a DSO that way a year ago. Not only that ....but the charge on the 0.05 uf capacitor (and leakage through it) can give you a nasty surprise.

BTW.... one of the first casualties of the poor economy by larger chains is Radio Shack. They announced today that they will be closing 1100 stores (20% of all they have) to save money. This really is not a big surprise as they have become a "phone" store mostly and really can 't compete with the pros in that arena. It has been a long road for them from the two stores in Boston and Springfield where they started. I forget which year but is was around 1950 or so. I really loved the early catalogs. Where else could you find stuff from MacIntosh side by side with Eico Kits?

Good listening
Bruce
