ElectroSchematics.com: over 1098 top electronics projects and electronic circuits with photos, datasheets and easy to read schematics plus how it works and how to build it. January 19, 2019. Vacuum Tube Amplifier. I received a request from a friend who want a 2A3 SE amplifier. Here’s the 2A3 I build for him. I used 6E6P as driver stage. The 6E6P are long life military tube which is very linear when connected in triode mode, Rp are around 1.2K , suitable for use as driver stage. The gain are around 25+ when using. When swapping driver tubes start with the volume setting very low and increase as necessary dependent on the drive level supplied to the amplifier. The acceptable power tubes are: 6V6, 7408, 6L6, 5881, 6F6, and 6W6. These all have slightly different levels of bias requiring different level of drive to reach full power. The 310 is actually both a 2-channel mixer,a tremolo-unit and a guitar combo. The two channels are identical microphone inputs with mixing capability. The first tube in the amp is used as a pre-amp/mixer as this tube is a twin tube where the outputs converge into one of the halves of the second tube. The cost of building this amp has been quite low, for me less than $300. 16 x Cisco SMPS modules - $100. 2 x halogen bulb electronic transformers - $20. 2 x Edcore output transformers - $60. 2 x GK71 tubes - $40. 2 x GK71 sockets - $16. 2 x 6S17K-V tubes - $4. 2 x KSG 1uf silver mica caps - $10.

So, in October 2010 I decided to go for my final version of the 801A SE amp. I upgraded to the Tango interstage version and the new power supply. My former 801A amps went back to Thomas and a bit later to Berlin, to an audio enthusiast and friend of ours, who has also gotten hooked on Mayer tube-amp magic.. Since I have multiple audio play back devices (CD, DAT, Solid State Recorder, Vinyl, etc.) I needed to keep using my current receiver and hooked up the tube amp via the pre-amp outputs on the receiver to power the speakers. I am using a Pioneer Elite 2 channel network stereo receiver in conjunction with the Reisong tube-amp.

I have always been interested in OTL amplifiers. Vacuum tubes have excellent bandwidth and low distorsion without global feedback and resistance coupled tube amplifiers as used in pre-amps often don't use any feedback at all, as an example the distorsion of a resistance coupled 12AX7 with 220 kohm anode resistance and 400V plate voltage is only 0.01% at 0.4V output voltage without any feedback. 6v6 Tube Amp Schematics - 17 images - 300b se amp, push pull pp el84 6bq5 or 6v6 6aq5 tube amp schematic with dynaco, power supply schematic for 6l6 5881 single ended se tube amp hifi, 6aq5 se,.

While it is a more modern class A single ended amp, the sound remains distinctively 'Sugden'. Upgraded with a fifty percent larger power. No problem (I figured). I pulled out the amp and did a web search for the schematic. As it turns out, PRS is quite secretive and doesn't publish one (I know because I asked.). They have a very simplified owners manual PDF that lists the tubes but that is all. Their suggestion was to box it up and send it in for an estimate.

In most designs, amp power-up starts heating both the directly heated 300B tubes (fast warm-up) as well as the indirectly-heated 12AU7 and 12AX7. (slower warm-up). In TU-8600R, the 300B tubes are heated after the indirectly-heated tubes have warmed up. A very tube-friendly design that will not overload tubes that have not fully warmed up. For a low roll off of approximately 10Hz: Ck = 1 / (2 * pi * f * Rk) Ck = 1 / (2 * pi * 10 * 220) = 72uF. So we would use 100uF. This is a pretty generic value for single ended amps and in many cases we wouldn't even bother to calculate it. Its voltage rating must be at least three times the expected cathode voltage..
