to the organisers Tonyboy, and Francis and John Agner, many many thanks for the chance to display our stuff...it was a whole lot of fun....

the EL34 pushpull was built with a quad of Shuguang tubes pulled out of a Cayin amp, circuit topology was based on the Mullard 5-20 but used a russian 6J9 pentode as input and the 6CG7 at LTP splitter instead of the ef86/12at7 in the original design, justification being the 6J9 has higher transonductance, and the 6CG7 can run higher currents to drive the EL34 grids with more gusto....

the 6C33 set used M18 cores which admittedly was it's achilles heel, upgrade path would be to use C cores, Edrel has some to try....as usual, the sets were very good at the mids and highs as expected...

truth to tell, no boutique parts, no exotic branded caps/resistors were used is building the amps, but generous filtering was incorporated into the power supply, and then the use of common mode chokes wherein both the positive and negative side of the psu was choked up so that noise common on both sides of the line are attenuated well..

Tony and I achieved a milestone i am proud to tell......there was this guy who came into the room to listen, looked at the sony 4 inchers and them came up to me and asked, sir where is your subwoofer? :D :D

that we were able to trick his ears that he was listening to non-existing subs was the greatest compliment we got in two days..... ;) ;)

+1 here. Special thanks to Francis and Tonyboy for giving us the opportunity to showcase our creations. Likewise, to Jon, for being the spokesman for the group. He logged more man-hours in the room than I did :) Lastly, to those who visited the DIY room. Your appreciation of locally brewed audio gears inspire us to continue to build and hone our skills.

Maraming salamat!!!

as always, a treasured friend, Edrel is the man when it comes to export quality traffos....we share trade secrets, so that anyone shy to ask me can ask edrel, we also share tubes, we are constantly on our toes sniffing around for throw away tubes and give them second chances.... :D

Congratulations to all the local brewers for taking the challenge and showing your creation/s to everyone to be listened to and appreciated :) You guys are the star of the room, I'm just manning it :)

To those who found time visiting rm 446, and listened to the gear our resident DIYers here have made, thank you for taking time to visit, sit down and listen to the music played from these gears :D :D :D It's the most basic and simplest room in the Nov Hifi Show, but as we have said before when the DIY room was first introduced in the Hifi Show, it's in this room that everything starts :D :D :D

To VD, TonyBoy and the rest of the Nov Hifi Show group, thank you for allowing these DIYers to show their creations for everyone to hear :D :D :D It's been my pleasure and privilege of assisting everyone in rm 446. :D

Cheers.

Bravo to local DIY talent. This room proved you don't have to spend much to achieve superb sound. Loved the sound coming from the mini folded-pipe full range speakers in this room plus of course Tony's electronics and Jon's turntable. Congrats.

Hehehe, actually, kaya ata gumanda tunog after kasi naging "öil capped" lahat ng tube amps sa rm 446 because of the lechon :) Tumaba tunog pagkatapos :P :lol: :lol: :lol: :lol: Umabot sa Puresound yung lechon kaya naging mas pure ang sound :) :) :)


BTW, thanks to VD for the lechon :)
