Recommendation for a quality repair center
Hi. I have a Graaf GM20 OTL that I really like which blew one of the 6c33c output tubes and may have taken out something else in the process. I inquired with Graaf Italy with no response. Does anyone know of a well versed competent service center to inquire to about repair? Thanks in advance.
