2 speaker - black
2 crossover (granite - black)
2 monoblok - tube PSE, kt 88, ecc 82, ecc83
1 preamp - tube SN7, ecc82, ecc83, RIAA
(all my design and construction)
Whole is not easy to do (except that it is patented). For example, casing has about a thousand laser-cut parts.

Have a nice day

T.E.C. TRIODE AMPS

Just to point out - it looks like the bridge for the bias supply is reversed. It should be generating a negative supply but the diodes in the bridge as drawn would give a positive supply.

Default Parafeed SE 6550 / KT100 (EL156)

Finally found a moment to post my current amps.
They are two parafeed amps with external PSUs.
The amps have been running on 6550s until this week. Now I'm trying some old Valve Art KT100 (actually an EL156 with octal base).
Still not done with these amps, as there is a low level hum in one of the units. Unfortunately my little Russian scope decided it's time for its retirement, so I can't pinpoint the source of the hum. If I can believe my DMM it is only on the OT secondary, not its primary.

The PSUs deliver several filament voltages and three different HTs : 300V - 400V (regulated), 370V & 1kV. This way I can use it for more than one amp. Now I have just the two parafeed monoblocks, but I'm building a SE 6L6GC and a SE 813 guitar amp that will be fed from these PSUs as well .
Eventually two parafeed QB2/250 (euro 813) amps will see the light. Or better: bring light to the room

Just found this on my computer and I think it deserves some exposure.

No spinning but it weeds out bad vibes from your system. Here's another voodoo idea to improve your sound and take some heat off:
