Since Class A din naman ang usapan... this has been on the operating table bago pa mag undas.

Punyemas ang bigat! At more than 70lbs, who needs to go to the gym?!

So since dual mono naman yung pila, effectively hatiin mo sa dalawa. . . Mas madaling buhatin.

Pwede rin bang lagyan ng VU meter yung amp since mahal din naman :-p

Baka naman maging dalawa na yun mahirap buhatin? Pero tama ka, mas ok na yun kaysa isang buhatan, ang hirap sobra naiipit kamachohan ko sa pagbuhat hays

Parang di ko masikmurang butasin yun front panel hehehe, tsaka added cost din ang maayos na VU ha, yun mga mumurahin walang kwenta ballistic movement.

Wala bang VU na pinapatong lang hehe?

Since mahal na sabi mo, ano ba naman yung extra para sa VU? Kung game changer naman, mura lang pag depreciated over 20 yrs :-)

Upcycling a Bosch power tool casing to store my special tools.

Removing the unwanted compartments using a Dremel tool with a cut-off disc.

Yes sir. The Dai-Ichi model as reviewed by JE Labs (not JD Labs

). http://jelabs.blogspot.com/2015/08/dai-ichi-pt6-horn-tweeter.html

Like him, I am just trying to augment the high frequencies, maybe add a little air, just a bit.

Yup ang dami ko din niyan dati pang reserba namin magkapatid. As per JE Labs this one is the closest replica/clone of the original PT6. Though not the best he has tried, YMMV nga daw.

So far naman to my ears it does what it's supposed to do. Just waiting for some parts to experiment on baka mapiga pa ang performance.

I remember installing an Orange Chiclet Type of Condenser to slow down the sharp edges during those times, In the 80's IIRC the Gray PT-6 cost P700/each then the Gold version cost P1,200. Those were the days 12" Hokotone woofers & PT6s' then Diy booster w/ 8 power Mat su shi ta power transistors on each side of the heat shink + KP-500= Boom & SitSIt, no vocals heard

Pero sumikat sya sa amp na paored with kp5 tPos naglabas na sya ng radio with amp and equalizer. Those were the days, simple lang hindi complicated. Pinaka mahirap lang sa akin noon is treating the hum pag nag accelerate hahaha bec of hogh tension wires
