Topic: Q: where to buy tubes

[tony]

sir tony this is not about the tube...its a favor reg my 6lu8 amp...ngayon lang lumabas yung problem kahit na totally off na yung volume meron pa rin lumalabas na sound and i think nasa number 3-4 if yung potentiometer ko kung may numerical decals medyo malakas . do i need to replace my potentiometer i use a 250k...before wala naman siya, hum lang which di ko pa na naayos yung issue sa hum... thanks sir.

dalhin mo sa house kung me time ka, most likely yung grounding ng pot mo yan,
if you can take a picture, send mo na lang thru pm...

Very nice analogy! Easy to understand.

Car tire analogy would have worked. Manipis na 4 gulong at sumabog na isa, at least replace both front tires. O mas mahirap intindihin logic?

Good PM to all.
I am thinking of changing the tubes in my amp - Cayin A-70T - the amp currently has KT88 tubes.
Hesitant lang ako to change tubes kasi may bias adjustment (?) pa yata na dapat gawin
I would appreciate it if you can help me understand this more and maybe give options how I can go about my plan?
Btw, sobrang bigat nung amp and mahirap buhatin but kung no choice for the biasing then I will do it.
Thanks again!

BTW, apologies if this is the wrong thread to post this. Thanks again!

you will need a small tip screw driver and a voltmeter, best to ask Cayin for instructions...
not that hard to learn....

maybe some of you know this already, but just in case,  another local source,
and thanks to the local guitarists, they drive the market for tubes...

Meron na ba naka order sa tube depot? how much inabot shipping and taxes?

Thinking of Gold Lion tubes if worth it.... thanks!

[tony]

Ouch... yun nga katakot, minsan mas mahal pa sa item, making it parang "ndi worth the price"

[tony]

magaling silang mag-imbento ng babayaran,
kaya ako pag nag-order ng tubes, binibilinan ko na
kahit ano mangyari, huwag sa fedex...
postal service lang okey na rin....kahit magbayad ako ng 500
hindi masakit sa kalooban...
