Been agonizing over posting this here or not. The world is full of EL84 amplifiers - who needs to see another one? I built this for two reasons: To have a tube amp to use while I refurbished my old one, and to have a unit I could surprise people with when they learned what 15 watts per channel can do.
Had a lot of fun designing and fabricating the PCBs, punching, drilling, CNC milling and laser-etching the chassis, soldering and testing... this one took about a month of evenings and weekends and represents an investment of $1400 NZ
It's the best-looking one I've made so far, and the fastest turnaround.
Technical and performance details, schematic, and more photos here.
One of these days I'll make something that doesn't look like such a rats' nest inside.
The Silicon Centipede is the microcontroller for the remote control... the RC allows remote power switching, input selection and volume control (motor driven).
This thing's been pleasing us with its performance and surprising amount of authority it exerts over the fairly inefficient KEF speakers, given its small wattage. It certainly lends credence to the myth of tube watts being different from solid-state watts. It passed the Salmonella Dub test with flying colours.
It weighs about 10kg with the big transformers at the back. I don't have any small children in the house so I'm happy enough leaving the tubes exposed but I see most commercial gear offers optional cages or shields over them. The big power tubes get up to around 160ºC
Planning to take this to a few peoples' places and try it on various different speakers.
I see a few people around building tube gear. wonder if there's enough of us for a get-together/swap-meet some time?

Item: VTL compact MB100 monoblocks
Location: blue mountains NSW
Price: 2000 ONO
Item Condition: very good
Reason for selling: thinking of trying something different
Payment Method: Pickup - Cash, Paypal( +3%),transfer
the MB100s have a wide and deep sound - clear with heaps of tight punch. they will drive most loads comfortably with plenty of headroom. they are heavy and very well built- quite industrial. one mono is running the original VTL 5ohm output transformer, but the other runs a good quality but non-original 8ohm transformer.. i have listened to these extensively and can say that there is no variation in sound quality between the amps . if there is a negligible difference in audible output between them then it may be ironed out by using 12AU7s in one and 12AT7s in the other or via your pre but i have generally not found it necessary. these are 240V. 4 X EL34 XF2s and 4X 6CA7 EIs. i have included specific photo of scratch on one transformer .
Item: Antique Sound Lab Hurricanes
Item Condition: Excellent
Reason for selling: Too many Amps
Payment Method: Pickup - Cash, Paypal, COD Only
Here are my Antique Sound Lab Hurricanes in excellent working condition.
200w in Pentode and 100w in Triode, running 8 KT88 in each block which can be switched out to 6550, KT90 or KT 120. By altering the tubes you don't get an increase in power but alter the sound signature as all bias stays the same regardless of tube.
Pick up is very much preferred as they weight over 30kg each. Would be willing to drop off to pack n send for them to pack if required.
Have original manual also
