This One Was A Complete Head Scratcher

Had an old prototype of mine from 2011 come back into the shop recently after it experienced a catastrophic tube failure and an equally catastrophic visit to a ‘tech’ that ended up with the amp non functional and leaking smoke. Join me as I regale you with the tale of delving deep into this amplifier in order to find the invisible problem that was causing such calamity. Do you have a broken or otherwise wonky vintage or boutique tube amp? I can fix it. www.tungstenamp.com
