1.jpgK-16LM 16W Mono Tube Amp Kit7163 viewsThis is the K-16LM mono 16W tube amplifier kit, with Russian PIO capacitors and carbon composite resistors. This Mono Integrated Tube Amplifier utilizes a 5670 triode and 6005 pentode tubes push-pull. It has been converted for use as a guitar amp.
Here are photographs of the guitar amplifier that was built with with tube amp kit.

MongrelChamp.jpgFender Champ 5F1 valve guitar amp.3927 viewsMy build of the Fender Champ 5F1. It is a SE three stage tube amp based on the 6V6 power valve and 12AX7 triode. The amps were first made in the late 40's up to early 80's. And re-issued in 2006. The original schematic had valve rectification. I added a 10H open choke. There are only two inter-stage caps and one by-pass cap on the 6V6 cathode resistor (not counting PS caps). I went for a Classic Champ sound by using cotton covered, single core, tinned copper wire as the hook-up wire, bees wax (Jupiter originals) inter-stage caps, an original Ozzie made 12AX7, Ozzie 5Y3 and 6V6 Black Glass (original). PS caps were increased from 8uf to 47uf and an effects loop added (between stage one and stage two). I didn't install the NFB loop from the OPT secondary to stage two. Instead I made the output stage UL (Edcor tranny). The amp is stable even when over-driven heavily. When hooked-up to a Pioneer PA 12" driver (4" Al/vented dust cover) it sounds excellent. Very clean highs and gutsy lows.

6V6-Lacewood-Amplifier.jpg6V6 Lacewood Amp3327 viewsThis is a 6V6 SE UL design with a 6SN7 driver stage (unbypassed cathode). Peak undistorted power is 3.2W RMS into 8Ω. Input sensitivity is 1.56v peak (1.1v rms) for full power. Designed for very quiet background, the power supply sports 15H of total inductance in two stages and a noise level of -128dBv. Hammond iron in the power supply section and Edcor output transformers.

DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier7016 viewsMy name is Laurie. I have been building and DIYing for 45 years now and happily will never stop. This tube headphone amp is from a thread in the Form.
The power connecting cable comes from a European Travel Iron I bought for $1.00 at junk shop. (220v/6A) They will be shortened when I find a perch for the amp and me. The sound is better than my ears have ever heard so I will be keeping this one for my retirement entertainment should such a time ever come. Wink It has worked from day one and continues to please me every time it is turned on. The tubes are JJ ECC88 / 6AS7 with a 5V4 rectifier tube. To spite it's small size the parts are quite easily accessed. I over built most components so it will outlast me I fear. The only change I anticipate may be the 6AS7 to a bottle neck glass to match the rectifier tube. I do have and use a 6080 tube, but i can tell no difference in sound. It will take more then a few hours of listening to get my ears better tuned.Feb 28, 2017

4-channel-400W-amplifier.jpg 4 channel, 400 W amplifier6012 viewsThis 4-channel 400 W amplifier uses Hypex UcD400HG modules together with the corresponding power supply.
The whole is mounted inside a Galaxy 330 x 230 x 80 case.
For building instructions, have a look at this project's wiki.
Two such amplifiers has been working for over 2 years in my lounge, driving Linn Komponent 110 loudspeakers which each have 4 speaker inputs.

E88CC-SV83-SET-Amplifiers.jpgDual SV83 SET Amplifiers6250 viewsA mirrored pair of SET amplifiers, presently being used in bridged mode. All P2P construction using silver solder. I included a "Hazen grid" capacitor and input tube bias change switch. The single mA meter displays individual output tube bias current with a Left/Right switch. Edcor XPRW178 power transformer and GXSE10-6-8K output transformers. Upgraded caps to Jantzen Audio 1200V Z-Superior. Upgraded resistors to PRP PR9372 Audio for metal film and TAKMAN REX for carbon film. ALPS Blue 100K attenuator. The power supply uses a RCA 5U4GB rectifier and Hammond 156R choke. Matched pairs of Svetlana SV83 for power and JJ E88CC for the input tube.

6V6-Push-Pull-Amplifier.jpgPush-Pull (PP) 6V6GT Tube Amplifier5201 viewsThis 6V6 amp was built following the DIY Push-Pull (PP) 6V6 / 6V6GT Tube Amplifier Schematic. Power Supply transformer and Output transformers are handmade in Argentina by NavasBaccino. I'd like to thank Brad S. for the help. The sound is amazing and clear, free of distortion.
