Hey All,
I’ve started my build of my #002 hybrid type clone.
It’s built off of a Ceriatone chassis.
I’ve designed a new front panel which incorporates dual foot switchable MVs with front panel switchable/foot switchable reverb defeat on MV2.
It will be running a 12BH7 cathode driver.
Most importantly, all transformers have been custom-wound for the project and are HUGE!!! A part of this is due to wanting to go crazy with lowering the noise floor, so all nine pin tube sockets will be fed 12VDC as a heater supply.
I’ll keep everyone posted as I build, and if you have any questions, don’t hesitate to hit me up....

Re: My hybrid SSS-002 build
Can you give us more details about the transformers? Where are you getting them custom wound... and would love to know if you think it really did make a difference in how the amp sounds.

Hi Dan46n2,
There's a few differences.
In the output TX I've used a combination of output and power laminations and the primary wound to 2K.
The power TX has a VERY big 12V winding to provide current enough to heat 5 12ax7's, a 12bh7, 4 relays and lighting. It also has a 90V winding for bias. 750v (375-0-375) HT at 250mA.
The choke is 5H, 100 ohms.
Most reverb TX's are wound to 8 ohm yet feed a 10 ohm impedance, so to better match my reverb circuit I've had the reverb TX wound 2575 ohm/ 10 ohm.
They're wound by Voller Transformers here in Australia. With postage of typical Hammond type stuff here to Australia its much cheaper, and I get to specify every part of the build, which is nice.
Transformers are such a hot topic, so I'm not getting into the "sound" discussion. I've made a lot of amps for myself, and I know what I like the sound of, so I go after that. One of my main aim with this build is to bring the noise floor down as far as I can, hence the stupidly overcooked 12V supply!!!
Should be a fun build...

Hi Troy,
I was chatting to a friend a few weeks ago about Voller transformers. He didn’t know if they were still winding them.
I was thinking of getting some made, keen to hear how your build sounds.
Thanks,
Aaron

He prefers not to. I’ve known Paul for a while and he always seems happy to help me out on a project or two...
