PYE Hf25 Power Amplifier You are looking at a pair of pye hf25 valve mono amps! although they look tired and the paint is horrible, these are one of the best amps made period ! The iron on these is fantastic, these have been modified years ago to el34 and 6922 by Joe Rassmussen, just look at the work underneath two of the main power supply caps on both monos are not in use, so only two need to be replaced on each mono and then I would think they would spring into life! these could also be restored to their former glory, it’s been done and documented on the net. MULLARD 5-20 is also a possibil
This is a fair ask, sitting almost exactly on the A$1,420 median of the recent AUD comps and comfortably inside the middle of the market, not a bargain but not ambitious either. At A$1,400, it’s essentially priced where a well-bought used example should be, especially with only three comparables to anchor it.
What makes it worth a look is the reputation of these older Pye power amps for straightforward, no-nonsense performance and good vintage value when they’re original and healthy. If it’s clean, unrestored, and fully working, the upside is in getting a solid piece of classic hi-fi at a sensible number; just verify service history, noise on startup, and whether any key parts or connections have been tampered with.

Pye is a historic British audio brand founded in 1896 in Cambridge, England, by William George Pye, a former Cavendish Laboratory workshop superintendent. The company quickly grew into a major industrial force, eventually comprising over twenty distinct entities that spanned telecommunications, broadcasting, and consumer electronics. While its early legacy is rooted in radar and radio communications, Pye's transition into high-fidelity audio during the mid-20th century established a lasting heritage that bridges vintage engineering with modern studio technology.
The brand is primarily known for its professional studio equipment, including high-quality audio amplifiers, pre-amplifier modules, mixing and switching units, and compression amplifiers. Pye TVT, established in 1960, became a pivotal name in studio recording and broadcast transmission, producing state-of-the-art gear used in seminal recordings from the late 1960s through the mid-1970s. Unlike brands focused on consumer turntables or headphones, Pye's core identity remains anchored in robust, analog signal processing and studio-grade amplification designed for professional environments.
In the current market, Pye occupies a unique position as a revered vintage-collector brand and a niche boutique entity for professional audio enthusiasts. Its reputation is defined by high-end, analog purity rather than mass-market mid-tier availability. Following a period of dormancy after the studio division closed in 1986, the brand was revived in 2020 by Avedis Audio in the United States, securing rights to restore and expand its legacy. Today, Pye is regarded by knowledgeable buyers as a symbol of classic British engineering excellence, appealing to those who value historical significance and uncompromising analog performance.
