Yeah... I know he is busy.
Lately, I have been using Audio Amplified which is located along C5 libis. Its on the 2nd floor of Madison Square commercial complex which has BIG GUYS PIZZA at the right side of the parking area and a Crispy Pata stall on the left side of the parking. You cannot miss it because it is beside a spa 'na tinatawagan'.
Anyway, they are open from 10am-6pm, Tuesdays thru Saturdays.
Look for P.J. or Mark. The rates are reasonable and usually are quick to fix guitar amps. Not only that but they have a supply of German made Capacitors for audio use which makes it easier for them to immediately fix capacitor problems. They also have chinese tubes.
I have decided to recommend them to help those on the forever wait list of Mang Raul. By the way, they are less grouchy, too. I cannot guarantee though that every repair goes without a hitch but so far so good FOR ME. Besides if they deal with hifi tubes amps, I guess guitar tube amps are a walk in the park.
P.S. I have nothing to gain by endorsing them... I just want to share the love to those who cannot wait. Also, I want to point out that I live in the area and near -- that's why it easy for me to have my amps repaired.
