sir jetok thanks. 
you mean, price will depend on the parts to be used?
Yup price will depend greatly on the parts to be used. But please try to be very extra careful when people claim that the equipment that you'll buy or the parts to be used are quality parts and not "fake" nor the "el cheapo" ones that can easily be bought at raon. But please do bear in mind that not all quality parts may have a very desirable end result. This also depends on what circuit it is to be used on or how the circuit is to be implemented. Remember , you don't want to put in diesel on a gasoline engine.
how will i know if the parts use is premium and not premium? di ba mahirap malaman yun for the beginner? is the branded tube amp is using the so called premium parts?
Premium from not premium?
.............. Hmmmm............ Nice question. First, you really need not be an expert on telling whether it is premium from not premium. Try to research on the parts mentioned in this forum or from other forums. Ika nga nila "new words i learned". Definitely there are many pics and articles available in the net regarding these parts, if you want i can post some. Another thing, try to seek advice from other forum members, "technicians" or DIYers. There's no harm in trying to know different opinions, bro. Mahirap naman kung masyado kang maniniwala sa isang tao lang, diba.
Minsan ayaw pabuksan yung equipment para di ma-void yung warranty achuchuchu...... yun pala para di mo makita na fake or cheap parts pala ang nakalagay pero the price they're asking is for way beyond the price for premium parts. Sometimes some sellers or technicians will even go to the extent of blurting out so much technical stuff or even inventing brands and part names (errrrrrrrrr....
) just to pull-it off.
is the branded tube amp is using the so called premium parts?
Nope not all branded tube amps use premium parts. Well, some or most of them use only standard or should i say ordinary parts. Why? Basically, it's really to cut down on production cost which in turn reduces "pass-on" costs to the market. In other words, para maibenta sa abot kayang halaga.
just my 2 cents worth
