I doubt that anyone here in pdvd has that speaker, so your only basis would be the amps wattage and the speakers efficiency. How the combo will perform together is anyones guess

honey badger is classAB, F5 is classA, you decide....

pero mukhang mas madaling gawin ang F5..

salamat sa input sir Tony. class AB muna siguro. mukhang di bagay tong F5 dito sa Texas.
sir Tony san kaya pede makabili ng PS boards para honeybadger?

Are you talking about the F5t or just the F5? These two are different from each other, at least in terms of construction. The F5t v3 is the most powerful of all the F5 class. The F5T is better off as a monoblock but you may want to check your wallet as a 100W Class A into 8 ohms would require a constant draw of 12A from your PSU and a heatsink the size of which should match the dissipation.

I have the all three amps, the HB, the F5 and F5t but the secrecy clause in my contract restrains me from posting pictures of the latter.

Btw, I wrote the official HB and F5 build guides for diyAudio. I hope you find them helpful.

yes sir. salamat sa documentation. I'm quite surprised wala akong mahanap na thread about diy amps dito sa pinoydvd. sumakit lang ulo ko kakatingin sa schematic. sending you a PM.

PSU boards ba? sold out pa sa store, and I am still designing the new one. Although the last one I designed was a complete sellout, it will be more of a bad a$$ PSU board this time.

Variac's mom just passed away so I think he's kinda busy at the moment.

don't be surprised... PinoyDVD is not a diy site... you may want to go where tony goes, yun Philippine electronics site or something, ask him the link kung gusto mo local forums. but diyAudio is the best to go to if you want to build that amp...

The Honeybadger, which we named after a bad a$$ animal (funny video too), is an all-rounder amp. You can make it sound like a classic Luxman or a modern Mark Levinson by changing the way the cascode is configured.

It is a collection of topology evolution, mostly learned from all the best commercial amps in the world and all rolled into one. It is a very capable amp, but the only catch is you have to build one.

The F5T on the other hand is the answer to the most basic question any guy will ask about an amp which is "how many watts?". It is an evolution of the basic F5 and for the first time, Nelson Pass has offered a diy solution that can reach 100W easily in Class A fashion. With a carefully designed power supply, it can deliver over 200W into 4 ohms in Class AB. But the catch here is the power supply, to reach those numbers, it has to be built tough and most of the times, tough is expensive.

If money is not a question, you can even plunge into the EUVX implementation which is like Nelson's X-1000 Class A amp to deliver a whopping 1000W of Class A power to that MTM you are building.

At the end of the day, it is up to you to choose your poison...

i am using computer grade 3 inch can, 47,000ufd/100vdc caps rated for 105*C
and i am not using boards for the psu....

jojod has more info i think....

but you can check the boards against the bom and schematics...

sir tony and jojod, ok na ba itong Antek AS-4445 per channel?

tony · « **Reply #27 on:** Feb 18, 2014 at 01:45 PM »

pwede na....but if i were you i would go for 600va.... or two 300va...

i had a bad experience with ANTEKs, one of the two 300va toroid had open primary winding..
i suspected that it was dropped by the worker during production and landed on its edge...
so before you buy make sure of the return merchandise policy in case you were sent a lemon...

Makasingit lang po mga bossing...

Since you were talking about a transformer what is the correct formula for converting VA to watts? I have a trafo which will be used in one of my diy amps from diyaudio. I got it from a defective pioneer sx-939, it has a multi voltage input and a +-44v secondary output plus another set for the preamp and fm/am section of the receiver. The back panel says it
has 380w power consumption, would this be enough for a 100w diy amp?

if that 380 was printed at the back, then that means the total wattage of all other gears plugged into the back of your amp plus the amp itself is limited to 380 watts.

the pioneer sx939 is a 70 watt per channel amp originally, a bit short for 100 wpc, but you can use it if you have it.....
