I would take 25pcs. How much would that be? and how much shipping to Australia would cost? just padded envelope would do.
Thank you,
cheers,
Hello Fellow Techies, I'm Aaron. Pretty much new here on Forum .
I'm a 80's & 99's Stereo -JUNKIE from head to toe. 😂 Lol Raised up from the country and as a boy I had enjoyed the VERY Stereo I'm listening to today. My folks purchased from a nearby dealer .
✓ 1987 Fisher HiFi Studio Standards
. 220W A/B. Amplifier
The RS-884 TUNER AMPLIFIER
QUARTS Locked FREQUENCY SYNTHESIZER DIGITAL TUNING SYSTEM.
✓MODEL STV(SPEAKERS)15" 3-WAYS
+ Made DIY 9"MTM's Floorstanders Rms180 @ 8ohms(wired for 4 OHMS)
+
MONO 10"SUB(PLATE-AMP)
PLAN:
I WANT HELP WITH PREPARING MY PARTS LIST ORDERING AND Prepare FOR A SOLID FOUNDATION TO THE BUILD. IF ANYONE IS WILLING TO HELP ME HANDLE THIS, ID BE VERY THANKFUL FOR COMMENTS. EVEN IF THEY MAY BELIEVE I NEED TO RETHINK THIS CHOICE, IM LISTENING.LOL THANKS SO MUCH...
+
. I can't find SPECS as to how much power THE*BADGER*CAN PRODUCE

Firstly, the use of capitals is like shouting and is very rude. Its the best way to annoy people.
Next, this thread is about "Wolverine", a seriously improved and consequently more complex design that builds on the Badger. Wolverine is an EF3 and is capable of driving low impedance loads (speakers) at what ever level your power supply and heatsink will support. Typically people can expect 200W into an 8 ohm load with a 3 unit DIYStore case and a 50Vdc power supply. (If you do not understand any of that jargon please ask)
Further information, parts lists and build guide are found at page 1 of this thread.
Nobody take this advise please. Leave the cap as spec'd in the BOM as is. There is nothing to be improved on here.
Anand:
I’ll be at Burning Amp both days. Happy to chat with you if we can find each other.

Scott
Great build, and yes you are right, it's the best I have ever heard too!
I just completed a EF3-4 using Sanken outputs and Toshiba drivers, and wanted to share the following measurements with you all.
First test - Frequency sweeps from 20Hz to 48kHz @ 25Vrms into a 8ohm load every 5 minutes for an hour from dead cold power on. I ran this test to check stability and distortion over the time it went from cold to hot, as you can see that amplifier is very stable and does not drift.
Second test - Heat soak running band limited pink noise 20-20k @ 1/8 power(25 watts) for 1 hour, then ran the same frequency sweep as before and compared it to the proceeding sweeps. Note the scaling is highly zoomed in, yet the amp held the low distortion as before.
Third test - Power sweeps to clipping at different frequencies, and to see how well the distortion holds up at higher power levels. The amp runs around 190 watts @ 0.1% with 60 VDC rails from 20-20kHz.
Fourth Test - 1 kHz FFT @ 25 Vrms into 8 ohm load. I am using a 1kHz notch filter in this test. ----0.000027% THD | -131.37 dBr----

Your build looks great, absolutely love those green boards. I'm so happy that you have completed your build and your happy with the performance. Thanks for posting and I hope you enjoy listening to your favourite music.
Making progress on my build.
Both boards working perfectly power up and bias wise on 71Vdc rails

Obviously, this amplifier has a great potential, but to attain such results there must be something more. Could you, please, tell us what are the most important practical details that lead to such an extraordinary result.
