Hartkes have exploding capacitors on the circuit board...Aren’t Hartkes one of the worst sounding amps anyway? Them and G-Ks.
I’m sure the National sounds far superior. If they’re the same company that made resonator guitars, it must be good.
Be patient, yours will explode.well a decade and no explosions I guess I got a "good" hartke.
The National is a lovely little beastie -I too am a late 60's model-- - I like it probably not going anywhere anytime soon --- yes I believe this is a STRUM N DRUM rendering .... makes lovey boom vibes. 38 watts.... weird but o.k.
