Mint condition and 100% free of any scuffs or dings with less than 5 hours of total \"In Home\" use by the amplifiers one original owner. \u003c\/p\u003e\n\u003cp\u003eCapturing the overdriven attitude of music's most cherished Class A combo amplifiers, the Dr. Z PHD 110 takes the low-wattage, single-ended formula into the 21st century with expanded headroom and dynamic range. Tiny tube amps have reigned as studio secret weapons since the dawn of rock music for their ability to deliver raw, dynamic overdrive at reasonably low volumes. That said, for all their pint-sized power, most classic low-watters feature precious little headroom and a rather narrow bandwidth at high volumes. To rectify (quite literally) these historic challenges, the PHD 110 replaces the standard 3-tube tube complement of Fullerton’s 5-watt champions with an octal-based 6SL7 preamp tube, a KT 66 power tube, and a 5U4 rectifier tube. This configuration ups the PHD 110’s power to 10 watts, granting you pedal-friendly clean headroom without compromising on the even-order harmonics, dynamic feel, and early breakup that defines the single-ended recipe. Moreover, the good doctor rounded out the single-knob setup found on the most lauded single-ended amps with the addition of both a tone knob — inspired by an iconic Ivy League tweed amp — and a Master volume control that only bolsters the PHD 110’s early breakup potential. A lightweight and resonant poplar cabinet equipped with a punchy WGS G10 C\/S 75 watt speaker seals the deal, all adding up to a seamless blend of vintage attitude and boundary-pushing Dr. Z engineering.\u003c\/p\u003e\n\u003cp\u003e- Made in the USA, October of 2025.\u003c\/p\u003e\n\u003cp\u003e- Serial Number  JJ-55025\u003c\/p\u003e","brand":"Dr Z","offers":[{"title":"Default Title","offer_id":49846702506221,"sku":"210000158429","price":1950.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0085\/8118\/5613\/files\/zzxq0laa6mjeaah0pylc.jpg?v=1777566386","url":"https:\/\/musiccitycanada.com\/products\/dr-z-phd-10-watt-1x10-all-tube-combo-amplifier-2025-red-mint-used","provider":"Music City Canada","version":"1.0","type":"link"}
