| One of my Tubes on the Jolida 301A flickers Switchback..Where does the CJ pre-amp connect to ? I'm real happy with the sound I got out of the preamp tube upgrade. There is a major improvement over the stock Chinese preamp tubes. I didn't even need to burn in the preamp tubes to hear the imp... | |
| One of my Tubes on the Jolida 301A flickers Cool.I don't know if you tried different preamp tubes in your amp but upgrading the preamp tubes was the first thing I did. I upgraded the 12AX7A tubes to JJ ECC8003 goldand the 12AT7 to Jan Phillips 12AT7WC. The results are incredible! The upgra... | |
| One of my Tubes on the Jolida 301A flickers switchback, did a bias adjustment correct the problem ? | |
| Anyone have honest opinion of Jolida amps? I am a systems engineer. I work on my own stuff.I have an oscilloscope, j202 schematic, and my sons claim I have "mad soldering skills".. I bought this as a decent platform to build upon and tweek. I was amazed that all I really needed to do was u... | |
| Jolida 102B paired with Boston Acoustics A200??? Energy CB-20 sounds really sweet with Jolida too! 97db sensitivity means 25wpc is actually loud! | |
| Anyone have honest opinion of Jolida amps? Uhm.. the guy that said jolida = trash .. you obviously only used the cheap $3.00 stock tubes. I upgraded with JJECC8003s gold tubes for the preamp. USA JAN Phillips 12AT7WC for the drivers and let the stock EL34 B output tubes age a little. It so... | |
| Does anyone here own a Jolida 202/302/502 amp I am using JJ8803s Gold in the place of the stock 12AX7Aand a Jan Phillips 12AT7WC in place of the stock drivers.Hum is gone. The flash from the right channel 12at7 is gone.I paid $85.00 including shipping for this upgrade, well worth it. For a ha... | |
| One of my Tubes on the Jolida 301A flickers Check your bias! I bet the bias is off. What you mention about the tube flickering and distortion is what happens when you install new different final output tubes. get a digital multimeter, a small flat head insulated screwdriver and adust the bi... | |
| Lifespan of a quality solid state amplifier? electrolytic caps have a limited life span. No way around it.500k hours I think. Average use 25 years or more. Some caps can last up to 50years. It depends on the environment too. My 26 year old kenwood sounds like I am listening to a low bitrate ... | |
| Does anyone here own a Jolida 202/302/502 amp Thanks for the reply. I should have waited because the tubes are starting to sound great.After 70hrs of using the amp the sound improved big time! Even the soundstage opened up! While I was working out I cranked up some grunge from The Todies and ... | |
| Does anyone here own a Jolida 202/302/502 amp btw jolida also shipped me a replacement tube sine a 12ax7a was defective. That's where the 60hz hum was coming from. I think the filament was damaged. | |

| Anyone have honest opinion of Jolida amps? I own a Jolida 202s connected to a pair of energy cb20 speakers. To be honest my Miniwatt n3 sounds richer and fuller when connected to the same speakers. I am running a sweet set of nos tubes in the n3.maybe the Chinese tubes take a long time to ... | |
| Do I need BOTH amp and pre to be sonic holography? get yourself a good tube amp.sonic holography is just another phrase for sound stage |
