Just have to relate my customer service experience with THD and Ed DeGenero. I recently purchased a Flexi from the Emporium and when I received it something was wrong- tubes were getting extremely hot like they were getting way too much voltage. I e-mailed Ed and he promptly gave me a RA# to send it back to THD. I sent it and THD got it last friday. They fixed it and shipped it out on monday- no charge! Also are sending a new set of EL34's! They really didn't have to do this, and I certainly wasn't expecting it.
