Ghxamp Newest 1969M FET Pre-bile Amplifier Board 1969 IRF250 Tube amplifier Board Bile Dual Channel UHC-mos DC15-60V 1Pairs

пришёл order very fast. matches the description. комплектно all, signed all resistors, all items new. seller recommend.

Great amp! Beautiful sound! Go ready to buy good speakers!Lovely amplifier. Going for 15 minutes. Nice удивен, sound very pleased, especially at high frequencies, bottom is also missing. Nothing better for money is not found.

Very good op, faclile a fit but cepandant enough hard a set, the adjust can only s perform when charging with a pregnant source type MP3 player or better, A lab Alim d at least 30 Volt 3 amperes for reglege debut, Mid voltage S gets source running as told in stand l intensity high enough to adjust a 15 -16 volts that CI, the adjust l intensity a 30ma must be renouvellé after 30 minutes of operation with a adjust source off, Module no depasse No 200 mA operating either 6 Watts for (30*0.2) = 6 Watts.

Arrived VERY quickly, net charge, wash do not before soldering,Transistors No magnets

Product quite compliant description.

Large tube IRF250 version, Current 10-200MA adjustable, You can adjust

Current 10-60MA (0.01-0.05A) , 30MA (0.03A) sound is very good, the current need to increase the heat sink, do not pay attention! (Since the FET is a voltage-driven device, good results can be achieved without a large current. The 30MA is so nice that it is very cool. The high current is hot and the sound quality is the same.)

This PCB is compatible with the size of the tube process of gold resistance smaller tube can change their own

HOOD1969 is undoubtedly one of the most popular amplifier circuits in history. Designed by famous British audio house J.Hood in 1969, HOOD1969 has innumerable imitators worldwide over the past decades. Some people use it to compare with 300B amps, The sound is toxic, I believe most of the fans of its name has long been known. The following is the real HOOD 1969 original machine to enlarge
