Groups Buy for Supermicro Crystalline OPT 300B SE amp with Interstage driver stage.

[tube-lover]

Hi all,

I was planning a EC52/C3m DC to 300B SE projects.

I ask to factory already about this plan. Factory return was if I can accumulate amount to order. He will tailor made this spec to us & use point to point solder, all hand funish by experience technician. Do not use PCB lay out. All the Transformers such as OPT,choke,power trans & interstgae were OEM by Daburu audio transformers.

Let us discuss the project in here.

Every kit will finish over 90% only & tested already. I was afraid that funish amp diyers will lose diy interest & their country's tax!!!
Unfunish tube amp will only charge the parts will less tax!

But every diyers only need within 2 hours to finish & sounded.

pls see the photos of the super-microcrystalline core OPT which OEM by Daburu.

thx

thomas
