Pioneer TX-5A Tuner


2002-01-07 6:02 pm
Sorry I can't help you with a schematic, but I do know what you're talking about wrt the sound. I have a Sherwood 2000 tuner, and the day I bought it, it took me a couple of minutes to realise it was mono, so big and rich was the sound (it was tuned to a classical station). The TV and FM come from different sites at my new home, so I'm waiting for them to finish a new Tx tower which means I can point my big Yagi at the one spot to get both. 'Till then, no FM.

There is a website for tuner buffs, but I lost the URL in a recent crash. If I find it I'll post it. They may be able to help more. A Google search might turn it up.

Do you have a pic of the unit?
Thanks for the info. This guy looks like a top of the line guy. It's got eleven tubes and a nuvistor front end. It's got stereo with AFC, and AM narrow, wide, 110V or 220V, with a machined aluminum front plate, and a beautiful vacuum tube tuning eye that narrows as the signal strength increases. The sound is luscious! I haven't tried aligning it yet, but I believe it hasn't been touched in at least thirty years. Dust inside, before I cleaned it, was almost a quarter of an inch thick, and apparently, no tubes had been changed since the dust began accumulating. A matching amp tube was available, but I wasn't looking for an amp, although it looked mint. I don't have a scanner, otherwise, I'd zap you a pic. It's a great looking unit. Looks as good as anything on the market today! Again, thanks for the interest, and if you find the link, please let me know!
