If you are not well versed in electronics you should have the board installed by a qualified professional. There are lethal voltages present under the amplifiers chassis that can cause serious injury or death. If you are unsure of your ability, please heed this advice or simply do not purchase this item as it is meant for those with adequate electronic skills, proper tools, a working knowledge of electronics and a clear understanding of what safety risk is involved with the installation.
Guaranteed great sound with this board, I have used this setup dozens of times and it is really an amazing sounding board. Expect to hear the best sound after 8-10 hours of "break in time". The longer it plays  the better it will sound.
To ensure the best sound and overall results you should have a good working closely matched set of output tubes and good strong rectifier tube.
It is
recommended
to also replace the bias supply section capacitors, resistors and also the multi section capacitor while upgrading to a new circuit board.
