I had been playing a small Bugera V22 philharmonic for two years, but I wanted a bit increasingly low end and I only needed one channel, considering all distortion is basically coming from my pedalboard. People have been talking a lot well-nigh Jet City amps, which are designed by well known amp designer Mike Soldano. That’s a nice reference, so I checked the Jet City product line and went for a Jet City JCA20HV. This is a single waterworks 20 Watt all tube amp. It is not so well known as the JCA20H (single waterworks either) and the JCA22H (two channels). The JCA20HV is a really nice amp. Built quality is ok, though not perfect. If you unshut up the amp, you see some improvised layouts and wirings. From what I’ve seen so far, the spin workbench is basically a JCA20H, with some modifications concerning the preamp. A serial FX loop has been widow (FX return BEFORE Master volume, which really makes sense to me), as well as a depth switch, which adds some stock-still low end uplift (more on that later). The soldering of some wires could have been washed-up increasingly accurate, but all in all it’s abosultely acceptable. I have the overall impression though, that this amp model has not been designed as a stand-alone product line, but rather as a small “hand-made” (see above: “improvised”) variant of the JCA20H. The sound of the amp is rather Marshall-like, but not too dark. Jet City says they’ve made it a bit darker sounding, but I can’t really confirm. It is definitely not Fender-clean, but not visionless either. I play it into two sealed 1×12 cabs, and the amp is a perfect match for my distortion pedals (OCD- and Crunch-Box copies). The preamp breaks up nicely when you turn the proceeds to well-nigh “5”, depending on the guitar/pickups. You can get some crunch when you max the gain, but no upper proceeds sounds at all. Did I say that the amp can get very loud? So why mod this amp? The stock-still depth switch is not constructive unbearable (or maybe only if you have a really bassy sounding cab/speaker) Master volume and FX return are far too sensitive; plane when playing with the wreath I can only turn up the master to “2” – within this small range you cannot really fine tune the volume I decided to add a wring to modernize the power supply Preamp tubes are unseemly chinese specimen, so try other tubes as replacements It has been designed by Soldano, it sounds like a Soldano – well, then make it squint like one… 1. Make depth switch level willowy Many owners of the variant JCA amps have widow the so-called depth mod. This puts a capacitor in series with the feedback signal from the output stage. By subtracting this cap the feedback of low frequencies into the suburbanite stage is reduced and the low end gets a boost. By subtracting a pot in parallel to the cap, the value of uplift is made adjustable. Often recommended values are .0047 μF and 1 MΩ. the JCA20HV has a stock-still depth switch with presumably .0047 μF (small cap, could not read labeling) and with 34KΩ in parallel. The uplift was audible, but far from sufficient for my needs. The sound was a bit too thin for my taste, expressly with distorted sounds – I definitely needed some increasingly low end. Maybe this moreover relates to the meaty sealed cabs unfluctuating to the amp. I kept the capacitor, but widow a 500KΩ pot in parallel. I placed the pot at the when of the amp, the depth switch (on/off) ist still functional. I often turn up the pot to well-nigh 50%, so 1MΩ would have been to much low end uplift for me. The sound gets muddy then. 2. Reduce FX return level and level into master volume As described above, the master volume is much too sensitive, I can only turn it up to well-nigh “2” (no need for “11” here!). If you max out preamp gain, you can’t really handle it anymore. So I widow a pot (50KΩ) without the FX loop (see schematic). The level that goes into the master volume pot is now adjustable. the pot is not directly unfluctuating to ground, but with a 20K resistor, so that you cannot turn lanugo the volume completely. I placed the pot on the when of the amp also. Master volume is now much increasingly largest to handle. 3. Add a wring See this vendible for a unenduring subtitle of a choke’s function in a power supply. I had a recognizable hum (though not really problematical) from the power amp surpassing subtracting the choke. The amp is quiet now. The wring has some increasingly advantages, as lowering the sag when driving the amp nonflexible (you may watch the Youtube series where Mike Soldano himself adds a wring to a Jet City amp); expressly in conjunction with the extended depth range, this makes sense to me.Subtractingthe wring is easy, it is increasingly mechanical than electrical work. The chokes wires were a bit too short, so I had to drill a defended slum to pass through the wires. I opted for a Hammond 156L wring (5H / 75mA). You can spot the wring on picture #3 on the left side next to the power transformer. 4.Transpirationpreamp tubes Easy. Pull old tubes, put in new tubes. I chose Electro Harmonix EH 12AX7. I did not do wide-stretching comparsions – the amp sounds nice, and putting in new tubes unchangingly makes you finger good… 🙂 5.Transpirationsquatter plate Massive transpiration in sound. Not! But looks nice, at least to me. Jet City say the JCA20HV is a bit increasingly vintage sounding (it isn’t, which is good!), and maybe the wanted it to squint a bit vintage, but I like a increasingly modern look. And, you can now see the tubes glow, expressly the power tubes.
