Все равно ничего толкового не выходит.Такая вот информация проскочила на СЛОКЛОфоруме от испанца,обещался еще подкинуть,но видно дядька Дизель напугал его ФБРом и Интерполом он и заткнулся.
Hello guys.
The pics of the Herbert who exists in the topic are of the version 1.6. I have information about the version 1.8 that is different from the 1.6...
The V+ is of 475Vdc measured on 230Vac ( Mains in Europe ). All anode resistors are 120K for Tubes 1,2,3,4,5. Tubes 4 and 5 are with the same topology ( Common Cathode + Cathode Follower ). For tube 6 ( Phase inverter ) the values of resistors are 100K and 120K ( Instead of the typical values of 82k and 100k ). The caps associated to Tube 6 are all of 22nf. The cap between pin 1 and 6 of Tube 6 are 100pf ( SLO have a value of 47pf ). The value of 470 ohms in SLO, is 670 ohms in Herbert. .. the rest is equal ( of Tube 6 configuration ) respect to SLO.
The EQ circuit is typically like SLO in the three channels.
- For CH1 slope resistor of 100K with 220pf, 22nf for the rest
- For CH2 and CH3 , slope resistor of 39K with 560pf, 22n for the rest
The small, medium and large size red caps are Wima MKP10 ( 630Vac )The green small caps are ERO ( 4n7 ), the green large caps are Vishay 2u2 for cathode bypass in combination of 670 Ohms. This value of 670 Ohms are present in the majority of cathodes of all preamp tubes ( great capability of create distortion on each gain stage with this value ).
All resistors are metal film 1/4w except for anodes ( 1/2w ) and power supply.
Relays are Omron G5V-1 SPDT
DC filament supply for all 6 preamp tubes, AC for power tubes
See Ya!
