Erhart Audio Ray

The amplifier in good condition. Sound good. Will come with the Ge 6l6gc.  I only accept offer more than $700.00
Ray is

hand built to the finest standards using the well-proven 6L6G Beam

Tetrode tube, strapped in triode mode, and the 6SL7 dual triode.

Combined with the superb Lundahl LL1682 output transformers, this

single-ended amplifier will amaze you with its details and just the

right amount of bass and treble!
We

chose these tubes as each has been around for decades and have proven

themselves to be both reliable and excellent performers in tube

amplifiers. There are literarily thousands of NOS 6L6's and 6SL7's

available allowing the user to try out many different brands with

varying carachteristics of these classic tubes - also known as tube

rolling - which can have a positive effect on the overall sound of this

single-ended amplifier.
Ray

is shipped with a pair of factory new and matched bottle shaped Tung

Sol 6L6G and 6SL7. Please note that, it will take time for these factory

new tubes to settle in and mellow, generally about 50-100hrs!


Circuit: In

line with our philosophy of keeping things simple and allowing the tube

to work its magic, Ray's audio circuit is kept very basic with one

triode preamp stage, which is one section of the 6SL7. This then drives

one 6L6G power tube, which is strapped in triode mode, to give you that

much sought after and wonderful triode sound. And that's pretty much it!

Power Supply: On

the other hand, as with most of our designs, a lot of time and effort

has gone into the power supply to ensure that Ray operates at near zero

background noise level. We have achieved that by using a regulated high

voltage B+ for the main circuit as well as a regulated DC filament

supply for the single 6SL7. Most orher SE amps on the market use AC for

the filament of the preamp/drive tubes, which can and often does induce

hum into the circuit. This hum may be very low, but it is still there.

With Ray there is no hum, pure and simple!

Components: Only

high quality components are used in the construction of Ray. All power

supply electrolytic capacitors are Nichicon units. Film capacitors are

WIMA, and coupling capacitors are Mundorf MCap EVO series. Resistors in

the signal paths are Vishay CMF and RN low noise military spec film

resistors, and in the power supply we use Panasonic metal oxide power

resistors. RCA sockets are gold plated, and speaker posts are Rhodium.
The

printed circuit board is designed in house and manufactured to FR4-TG

standards. It is double layered with full ground planes on both sides to

ensure complete screening of the circuits.
The

power transformer is our own design custom manufactured by Heyboer

Transformers, and the all important output transformers are first class

Lundahl LL1682.
