3mm hole is advantageous. VHT Special 6 Harma Retro Philips 6V6GT G10 Green Kit VHT Amplifier Kits The VHT Special 6 1 x 10 combo fitted with Celestion G10 Green back an excellent classic British blues and rock speaker... It's a single 6V6 putting out 6 watts max. For R13, solder in a resistor with 220k. One where I get to do whatever. The closed‑back, 1x12 cabinet takes this to another level. Special 12/20RT Back Panel. You can find more info about this amp here: VHT Special 6 Ultra. To install this in the Ultra you simply place the circuit on the output solder pad of capacitor C23 on the circuit board as the signal input and use the C46 ground pad (see circuit board pic below) for ground. Improvement with other tubes, including 5751, 5965, and 12AY7.

012 F capacitors and 4 colors of 22 gauge wire. It was touted as a rock speaker made for loud applications. Near side of R39 is ground, far side is hot. If you use 250k Audio pots for bass and treble, and 100k Audio for the mid pot, the factory fixed resistors are roughly equivalent to 45% of treble pot turn clockwise (up), 30% of mid pot turn and 42% of bass pot turn. Need recommendations for a new 12" speaker (6w tube combo): -lots of bass -warm detailed mids, good for rock w fuzz/dirt -rolled off dark highs, clear enough to hear detail through the fuzz. The Special 6 Ultra comes with a fixed value Fender Blackface style tone stack and a classic Fender Princeton type tone knob for controlling tone. Unlike blowing a lotta money on tubes it actually works! The treble pot in a Fender tone stack is wired to function as a variable resistor. I did that because at the sides of the hole you'll hit the side panels. Special 12/20RT Send & Receive Level Controls. WARNING: A tube amplifier chassis contains lethal high voltage even when unplugged--sometimes over 700 volts AC and 500 volts DC. With the circuit mods the amp steps up to a whole new level and becomes a true harp amp.

Leave the leg as long as possible to ease soldering. Now unsolder the red and white cable from the volume potentiometer. Gold Coverage Includes: - Unexpected and unintentional spills, drops and cracks. To verify this mod is wired correctly place your multi-meter probes across R39 and measure the resistance with the switch in the low power 6V6 mode, resistance should be around 470 ohms. To calculate what the parallel resistance of the two resistors use this formula: Total Resistance = 1/(1/68000 + 1/new resistor). It is not limited to only quiet. But the risk remains with you, I just trust the 6L6 which do not need much heating. Number of bids and bid amounts may be slightly out of date. The kit comes with a Belton Medium digital reverb module, 2931 or 1951 voltage regulator (converts 6. Master Volume pot and Bright Cap inserted between the driver and power tubes (C23 and R38). That does not make it much louder, but there's a little more energy for the deeper tones. The Special 6 has only two tubes, V1 for preamp and driver and V2 for power. Killer closed-back tone at a price you can handle. With the reverb turned fully down the amp's analog signal is unchanged.

The heat shrink tube and the insulation must be removed a little, so the cables can get to the new tone potentiometer. Connect the wires from R14 and R16 to the outer two pot terminals (see diagram below). You can even use alligator clips to temporarily add a parallel resistor so you can try different value resistors until you get the volume change you want. The speaker Combined with the Special 6's cabinet, the projection of the speaker was such that it sounded WAY bigger than what its diminutive size might indicate. With a feeble 6W output running through a single eight‑inch speaker, it struggles to keep up at band practices; but as a recording amp, it punches well above its (very modest) weight. Even my band mates remarked on how big the amp sounded. This is due to the lack of negative feedback most of the time, not so large power (PT) & output (OT) transformers, small filtering caps, and huge filtering resistors in the power supply path. We have 100mA at 275V and 1. 4 Clipped Resistors & Wiring. The exchange of the first cathode resistor promises improvement. Added a capacitor brighten up the dark-sounding LO input. Just clip one resistor leg and bend it slightly out of position so you can re-solder it if you want to reverse this mod, then solder the choke wires to where R43 was soldered. I played it at several gigs and it was loud enough so I could monitor my tone, and just close-miked the amp to get it into the house. It's much easier to solder outside the chassis. In my experience, 5w-30w can. However, by dropping out the octal socket and twisting its position we could remove the blown resistor and install a replacement W22 series 7 watt ceramic body 470 ohm, our preferred type for demanding conditions. Low Power mode is perhaps a little disappointing by comparison, but still capable of yielding usable sounds. To install the choke you must replace Resistor R43 with the choke lead wires. There is no real need to change the stock tubes unless you are an inveterate tinkerer <(like me). 2 speaker jacks plus mono/stereo switch. 3 ohms so select 8 ohms. Output for the EL34 and 6CA7 with the bias switch was measured at 8. It turns out the location isn't that critical. The speaker, though good, is a tad bright for my taste. Other plan features include: - For products over $200, No Lemon Policy applies. But when I think some gear – especially amps – can be improved, I do some basic things.Vht Special 6 Speaker Upgrade Reviews

In fact, whereas I only had to turn the volume up to about 11 o'clock to get some grind with the original, I had to dime the amp and put the booster on and really dig into my strings to get some grind. If it fails for the same defect 3 times, it is replaced on the 4th breakdown. In this version of the manual, I limit myself to specify only one value at a time. Designed to be paired with the Special 6 or Special 6 Ultra heads. The return level control was a little more difficult to figure out because the Special 12/20 has a third 12AX7 tube between the return line and the return level control. Substitute 15k if you want more mids. Gear Double Trouble, neither of which can be had for $275 new. Special 6 Ultra Tone Stack Before Modification. The amp just sounds killer.
