and a 6U8 for each phasesplitter. The major change found in this reciever is it's solid state

rectifier in the power supply circuit. The 340B uses a full wave bridge rectifier to

produce the high voltage DC power for the reciever. The most probable reason for this departure

from a tube rectifier (or pair of tube rectifiers) was probably cost. The bridge rectifier

was most probably a lot cheaper, didn't require anywhere near as much space, and generated almost no heat.

Schematic for 340B

The 340B sold for around $400.00 in 1964. At that price, it was not for everyone. My 340B

also has the optional walnut case which cost an extra $24.00. Well, as the saying goes, you get what you pay for,

and my 340B is still working after 35 years. In fact, it still has most all of it's original components. I replaced

the bias rectifier and coupling capacitors between the 7591's and the 6U8's more for insurance against

future failure then for any sonic reason.

The H.H. Scott 340B is a fantastic sounding reciever that is capable of working with CD players,

tape decks and turntables with magnetic phono cartridges.

One feature I like on the 340B is the fact that it's bass and trebel controls are

each on their own dual pots. With the 299C, one pot is bass and trebel for one channel,

while the other is bass and trebel for the other channel. With the 340B, one "dual" control is

Bass for both channels while the other is trebel for both channels.

The 340B is a little brighter then the 299 or 299C, and had a little more punch on the bottom end.

Most of this is due to the stability of the solid state power supply. The reciever

sounds great, but lacks some of the warmth found in either the 299 or 299C.
