Hunter Amplifiers (Harvard 5F10).
Hunter Amplifiers (Gretsch 6156 "Playboy" inspired) "Esquire". This combo amp is Hunter Amplifiers' version of the 1961 Valco-made Gretsch "Playboy". It is completely hand-built and hand-wired. It's pretty true to the original circuit as far the audio stuff goes. It deviates from the original circuit by its use of a toroidal power transformer and the 6Н2П Soviet-made duo-triode around which the tremolo is built. The toroidal transformer provides more efficient, cooler, and less noisy power than traditional power transformers. And instead of the output tubes used in the original, it uses a pair of similar but less powerful tubes that were usually used in console TVs, stereos, and big radios back in the late 50s and 60s, 6BK5 beam pentodes. Two of these smaller tubes in a push-pull circuit create about 8.5 watts of surprisingly loud really nice sound. The tremolo is cool and can get downright "swampy". The original Playboy lacked an "intensity" control and instead had the level preset at the factory. But it called for adjustability, so we included an intensity control on the back next to the jack for the footswitch (which is included). It is fitted with a new Jensen C10R 10" speaker just like the original. The cabinet is all 3/4" New Zealand pine with some black ash trim, a birch plywood baffle board, a comfortable stitched handle, and four little rubber feet. It measures 17.5" x 15" x 7.25" and weighs in at about 20 lbs. This amp has 3 knobs on the front, volume, tone, a control knob for tremolo speed that doubles up as an on/off switch for the tremolo effect, and a power switch. There are three inputs, two of varying impedance and one "treble" input just like on the Playboy. It's "only" 8.5-watts, but it's plenty loud enough for most small venues and perfect for practice or recording. It has a complement of 6 tubes: a 12AX7 preamp tube, another 12AX7 used as a phase inverter, 2 6BK5 power tubes, a 6Н2П (6N2P) tube for the tremolo, and an EZ81 rectifier tube. Finally, it is wired with an IEC three-wire grounded power input plug so you need not fear electrocution every time you touch your strings. No transistors or semiconductors were used ensuring a completely authentic vintage sound
