Mang Rod, or Rod Teope is the best.....

Who're the best with push-pull/SET/SEP/etc?  Preamps?

Your favorite works by the pinoy tube masters?

I'm enjoying an EL-34 SET amp made my Andrew Sevilla.

Build quality is excellent.  Was expecting a bare chassi but got some nice wood sidings, too.  Andrew even put in a phono input and a bias knob for when I get into he mood of going for KT-88s.

Sound is sweet.

Must admit there's an ever-so-slight hum.  But I'm using dangerously cheap cables for now.  Have good cables on the way so hope that'll solve the problem.

I'm also using one made by Andrew Sevilla. Sonatina 5 PP EL84. I also experienced a loud hum when I connected the preout to my subwoofer. I rearranged the cables and the humming was gone.

was informed before that locally assembled tube amps would cost much higher than branded ones is this correct ?

yes, since mass manufactured amps are made with parts the are bought by the thousands, and labor costs will not be that high since
workers need not be highly skilled, in other words unit costs will be low...

units that sell for 100k can have a unit cost of just 10k because of that...this known as economy of scale....and manufacturing efficiency..

even if the locally diy amp may sell for only say 20k that would be more expensive in comparison....

it is in this context that i say DIY is more expensive....

there was a time during the 70's that parts were very cheap, i remember i could buy 12ax7 tubes for a peso each and power tube at around 30 pesos, but those days are gone, never to come back...

Okay na lang sana kung manufacturing efficiency ang reason ng lower cost. Ngayon, pati tolerances sobrang tight (to lower cost) kaya yun expected natin na tatagal for a decade would only last us 3-5 years.

planned obsolesence yan, merond expected life ang bawat parts,
na mga flourescent lamp factories nga binabasag ang mga lamps
pa over the life span ang batch tubes...

katulad nung isang sikat na British brand, pag bukas ko nung casing dahil gusto ko makita internal aba nagulat ako yung mga capacitor na gamit eh Jamicon,nag eexpect pa naman ako ng panasonic or elna dahil mahal din yung presyo ng gears nila hehehehehe

[parasound]

designed & assembled in UK.  kasi outsource lahat ng parts.

cost is king, when buying caps by the thousand pieces, they get the cheapest part that they can get that meets design specs...

Commercial manufacturers see their amps as product. DIYers, most especially those who design and build their own, see them as works of art which reflect how they view themselves and their craft.

^something casual users of tube amps will never understand......

[bass_nut]

AMX Audio (sir Andrew Michael Sevilla)... Hi-Fi quality customized tube preamps, power amps and integrated amps, WITHOUT breaking the bank  

[romymartinez]

Mine were built by DIYer Sir alexg (Alex Gendrano). Sounds great!

[jerix]

What is the price range are  we talking about for a DIY tube amp?
