ONE AMP IS FOR SALE. Its matching twin has been sold. This amp is a complete rebuild re-using only the chassis and transformers. Every other part has been replaced with new, modern, fresh components! It has also been repainted with a tough as nails epoxy hammertone paint.
You will have a hard time finding a better sounding SINGLE ENDED EL84 amp at this price! I have for sale 2 excellent sounding SINGLE ENDED EL84 stereo tube amplifiers using a Russian 6p14p-eb per channel with a 12at7wa RCA driver tube. This is the famous RH84 single ended amp by Alex Kittic that has been copied by thousands of DIY'ers all over the world. The unique aspect of this design is the use of local feedback vs. global negative feedback that is used in almost all audio amplifiers. The use of local fb makes for an excellent sounding single ended amplifer. Price of 300.00 is for 1 amp or 600.00 for the pair.
For this build, 2 RCA amplifiers from the 1960s with their superb quality output and power transformers were used. Only the chassis, power and output transformers are used. All other parts are brand new top quality capacitors, resistors, wires, etc. I have also installed a stereo to mono switch, just like the Decware Zen Triode, which allows the listener to use the amp as a monoblock for twice the power, but at less than half the price.   There is a stereo to mono switch on the top of the amp so you can run the amp as a monoblock for twice the power. This amp has all new matched parts in both channels for the ultimate in lifelike sound quality. Now upgraded with superb mil spec Sprague Vitamin Q coupling capacitors for that uncanny you are there audio experience. This gives a sound that is detailed yet smooth and sweet but very dynamic. Output power from a class A el84 is about 5 watts, but what a glorious sounding 5 watts. But even so, this is a very strong 5 watts and that can drive my JBL L112 speakers loud enough to send my wife outside!
Find out why those who have heard a single ended tube amp on efficient speakers never go back to any other type of amplifier. You have read all the hype the only way to know is to hear it for yourself. You don't need to spend big bucks on single ended triode amps with 300B tubes to hear the difference. Indeed, one of my SE EL84 amps that was sold to a fellow in San Francisco, sounded better than his 300B amp to he and his audio friends.
This amp is completely hard wired point to point for best sonics and audiophile quality sound and better reliability. All components are new. 5 way speaker binding posts, IEC type power socket with fuse, on/off switch, rubber feet and last but not least, a brand new paint job of blue and black hammertone for an excellent appearance. 
Special attention was lavished on the power supply which is one of the reasons for this amps outstanding sound. In technical terms the power supply which was simply capacitor input is now CLC or capacitor/choke/capacitor input. First the AC is rectified with Motorola FRED rectifiers for a tube like sound where it is first filtered by a pair of Nichicon 400v capacitors. It is then passed through a 10 henry inductor then to a 180uf x 400v nichicon cap. The result is a very dynamic sound, deep bass, sparkling highs, and outstanding headroom on loud passages. This amp also has excellent detail retrieval. On Dire Straight's classic album Brothers in Arms in the cut , money for nothing, Stings' vocals appear in the background slightly off center in the most realistic manner. Please check out the photo of the underside showing the high quality components used and the 14 gauge solid copper ground bus. The amp is super quiet with no extraneous sounds emanating from the speakers which makes it an excellent partner for horn type speakers. Don't let its small size fool you as the saying goes, great things come in small packages Thank you, for reading the complete text and visiting my sale.
Please remember that this amp is sold strictly as is. Caution is required as tubes are hot and there is no bottom cover to the amplifier.
Just remember if you are into headbanging, window rattling, neighbors phoning the police, loudness, this amp is definitely not your cup of tea. But if you are looking for a great sounding little amp for your den or bedroom this will make a Bose sound like pocket transistor radio in comparison and probably cost less and have a better resale value.
Per usual, this is a 60 year old piece of equipment and it is sold strictly as is. The unit is in excellent sounding and cosmetic condition with all vacuum tubes included.
I can perform upgrades and rebuilding for better performance and reliability
