Sweet. Love these old 4 tube amps! Like you, the Thunderbolt 305 is my absolute favorite!!

Made in Elkhart, Indiana!!! The company that is Dosy today is what was Elkhart Electronics that made these amps... These amp are made to be driven by a low powered radio like what was made in the 1970s. A browning or Tram would be perfect for this amp..

A nice oldie and a goodie.

My first tube amp had it 3 years works like a champ

Saaaaweeeettttt!!!!

Ótimo trabalho gualidade total bazuka Foz do Iguaçu pr Brasil

Hey mr rooster nice amp i haven't seen one of those in a long time good morning to you

i had a Thunder Bolt 305 when I was in high school. i wish I didnt trade it away.

Where you located at

I have one of these amps. Do you know someone who repairs them? Mine popped some caps or something and I would like to get it repaired. They have a powerful warm sound on the audio when you use these little heaters.

Is the driver supposed to light up ? Newbe here.

Pretty neat!

Nice old amp

How much you asking for the box
