I have a Vincent SA-31 and re-capped and replaced the tubes with some Russian 6N16B-V's and it sounds fantastic! I have quite a few left over so I am wondering if/how I can utilize them in a modified version of the Color Preamp? I bought a Hammond 262EE6 transformer (120V Sec@ 93ma + 6.3@1.2A) hoping I could use it for this project. Any advice on how the schematic could be modified for their use would be much appreciated!

Hello all and new to the group.

I am very fortunate to have an old friend of the family starting to teach me in building amps. Walter, my teacher, owner of SAR Labs in Winnipeg. Well known for over 60 years in the audio industry. Designing and hand building all kinds of equipment. Walter’s main signature design are mosfet amps.

The pictures shows my second point to point wiring project, a design of Walter’s. It was fun to design and great to listen too. Still tweaking with tubes and feedback loop in the design. Sorry, I don’t have permission to share his schematic. I probably can’t answer any really technical questions either.

Hope the link works.

Hello,

I just finished my 2nd Skunkie moded Riesong A 10/ A12. It has been so satisfying to tinker and hear the improvements in sound.

On this 2nd one, when I turn it on the amp plays marginally loud, then gets quieter until the maximum volume is just a whisper. The volume knob does affect the volume.

I've swapped tubes, still quiet. re-flowed most of the solder joints. Voltage at B1 is around 300v.

Any thoughts on where to look?

Much appreciated

Something I had been pondering for a long time, years actually, finally became reality this September. My A10, sounding gorgeous after my Skunkie schematics circuit update, to my eyes looked a little too blingy, with all shiny stainless steel. I wanted that serious botique-build look with wooden sides, like the super expensive japanese ones... A youtube video with a guy making a fixture for a common handheld planer, making it able to precision plane wood, kicked me off. Pao Ferro wood for making guitar fretboards, bought from Aliexpress, became the candidate.

I'm Christine, I'm based in the UK and have built tube guitar amps and solid state hifi amps before.

It's about time I made a hifi tube amplifier.

Love Skunkie's youtube channel.

WIX forced a change from their "Forum" to this "Groups" thing. Now 100% sure how this works but I hope it's seamless on your end! Kinda doubtful it will be but there was no option.

I built and enjoy Skunkie’s EL34 amp earlier in the year.

I had been using JJ EL34L tubes in another amp prior to using them in the Skunie amp. I have noticed noisy tubes on amp power up. I didn’t think much of it until recently I started hearing some distortion. Swapping the tubes in the amp, the issue followed the tube.

I was going to order another set of JJs but wanted to see what tubes others are running or prefer.

To be clear, the amp did not cause this problem, I have had the tubes for a while. I’ve also been known to leave amps running overnight. By accident of course.

The JJs are a good value so likely I’ll get another set regardless.

Hi everyone. I bought my 1st tube amplifier ever ( I born in 1963 ) in December 2020, a Reissong A10 directly from China- HiFi ( = A12 but 6N2 driver tubes ). After successfully rebuilding it according to Skunkie´s schematics, I decided to install remote volume control. I bought a remote volume control from Aliexpress, 100k resistance, just like the one in pict below.

It is very crowded and cramped just behind the original volume pot, and the Aliexpress motorized remote pot is rather bulky, so there had to be some engineering work done to install it. I realize this build may not be for everyone, but possibly someone would like to try it out, and then I could give som hints on details of my own installation.

After quite some tinkering, it all worked, and it was really rewarding.

Hi,

It took a while, but I put together an EAR834 clone using a Hammond 369 Transformer and 3 electro-harmonix 7025 tubes. I have built one board from scratch, and I also bought a prebuilt one to test as well to see if I was doing something wrong.

I have an st-70 that I tried as an amplifier and a cheap chinese one and both give me the same results. The first track is the sound it makes when it first gets power. IT settles down after a minute. The second clip is the music at about 1/3 volume and it sounds terrible. The recordings are with the board straight from ebay with no real modifications. I also have one I built and they both sound the same. The only thing I can think of is maybe the solder connection to the rca jack is not the best. I am using…
