Hello everyone,

I am a new member to the forum - just registered today.

I have a Heathkit A-7D Audio Amp I just purchased and I understand that there are some modifications that have been made to it over the years. Would anyone in the forum have any knowledge as to where I can find those mod's. Thank you, I would appreciate it.

Hi and welcome to the forums. Moved your thread from Forum Problems to Tubes category where it fits. Read the forum's rules (top menu) and have a look at the categories (left menu) to learn more about our site. Wishing you good DIY experiences. :captain:
 
I would just add that when asking for technical advise it is always helpful to add the schematic for the device to the first post. Most users don't have the schematic for every device close to hand and that means they must search for it on line. If you provide the schematic, even if you have to search for it, then more people can respond.
