Demonoid, плюс тебе за схему, сегодня собрал на макете. только не знаю, что то хайватовский темброблок мне как-то не очень понравился. видимо уже привык к фэндеровским регулировкам и такой тб мне непривычен, все время хочется середину убрать:) вообщем буду собирать на чистовую неторопясь с нормальными деталями.
Спасибо
Мне самому понравился этот усилитель, очень нестандартный, как раз такого нехватало, для занятий дома самое то. На счет темброблока, человек снимал схему С7 утверждает что она как у Hiwatt Custom, этот аппарат весьма на любителя. Диапазон регулировок большой зато.

Matamp С7:
The
Matamp C7 is one of those fashionable single ended amps that we see everywhere now. My schematic is incomplete because I drew it from pictures only. Nevertheless, it features a few interesting points:
_ the tonestack design is taken straight out of a
Hiwatt Custom, although the identified values are different. This kind of tonestack isn't very efficient in a Hiwatt (at least the ones I have played including mine), but it is very powerful in Sound City amps.
_ the valve after the return of the effects loop doesn't have a resistor on its grid: this is looking for trouble (if an unconnected cable is plugged into the return jack for example). This omission is strange since the reverb recovery stage has one...
_ the power tube cathode resistor doesn't have a bypass cap: I haven't tried this in my builds but I assume that the result is reduced power output (as in "not increased") and some kind of compression effect.
_ the ON/OFF LED positive voltage is taken from the power tube cathode resistor: simple and smart,
_ the Attack control is an improved "presece" control: it gives a kind of cut when the wiper is close to the global negative feedback resistor, and boost when the wiper is on the other side. Again, smart.
Except for a few niggles, these Matamps are very well made (better than the ones from the 90s actually). They look good, sound good, will probably last along time and are priced more competitively than many of their competitors.
