It’s like the wholesaler in Saskatoon that had parts for tubes as well and he sold to radio TV repair shops but sold to a pair of fools that soon started squabbling and then went belly up! This previous owner now works at B&E Electronics, or as the slang goes Break&Enter in Saskatoon which is nothing in comparison for these items. Probably have parts to build a solid state vibrator or a solid state 6AQ5 or 6V6 but other than that, not much else. Their capacitors have low voltages as well and are probably made by little yellow fingers on kids wearing diapers in an off shore sweat shop. .
