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 the same ones as in the video. Any thoughts or ideas would be greatly appreciated. Thanks, Greg
