Gentlemen:
I found a very nice Motorola HS-442 mono tube amp at a Hamfest yesterday. Very clean. Likely needs recapping but I am trying to find a schematic. Also if anyone knows the output power of this amp. It has a pair of 6V5 tubes in push-pull in the output. I only paid 10 bucks for it but it looks extremely clean, no rust on the chassis. Any help would be greatly appreciated. ---Marty, KK4RF, Suffolk, VA

OOPS! I meant to type in "a pair of 6V6" tubes instead of the incorrect 6V5. Sorry for any confusion---Marty Harpen, KK4RF

It's covered in Sams 282-10.

Power output of PP 6V6s can be between 5 and 15 watts depending on B+, which can be anywhere between 250 and 350V.

Many thanks to David and Johnnysan. I will put in a request with Sams. Just curious if you guys knew what the output impedance of the amp is, i.e. 3.2 ohms, or 4 ohms, 8 ohms or whatever. Thanks again, Gentlemen.---Marty, KK4RF

I have that Sams; if you PM your email address I will scan it for you. It's 4 pages.

1 speaker is 6.8 ohms and the other is 15 ohms, so my guess would be that the impedance is around 4 ohms.

Gentlemen:
Thanks for all the info. I was able to download the 4 page description on Sams, 282-10. Thanks for all the offers of help as well. I hope to recap this nice old amp in the next month or so. Need to figure out what I'll use it for but I'll find something. Thanks again, Marty, KK4RF
