I had my 2 Tube amps checked and fixed by Mang Raul the just recently.
He has a lot of schematics of tube amps to check to make sure your amp is working properly. he even had a schematic drawn/copied for one of my amps.
Mabilis gumawa and pulido. First time I went to their place pinameryenda pa ako ng siopao at coke. lol.
Very knowlegable in all types and brands of amps. Sana he teaches to share the knowledge, parang apprenticeship.
Easy to reach coming from Espana, basta text/call for scheduling, then make sure your side mirrors are tucked in baka masagi ka sa street nila, hehe.
I asked him about his custom amps and according to him a simple 1 watt amp will cost 5K while a JCM 800 clone wil be 14K all in parts and labor. That's a vast difference in price to the 115K JCM 800 in JB
. Your amp is done in 3-4 weeks.
He's a tube amp expert. I just hope he teaches his craft to spread the knowledge.
