Traynor Custom Special Bass Amplifier Stack (Head and Cabinet)

This is a vintage Traynor amplifier stack consisting of a vacuum tube head unit and a matching large-format speaker cabinet. The head unit is identifiable as the Traynor Custom Special, likely the YBA-3 model, which was a flagship bass amplifier produced by Yorkville Sound in Canada during the late 1960s to mid-1970s. Physically, the units are encased in rugged black Tolex-covered wooden enclosures with a signature silver-grey grille cloth and polished chrome-style trim accents. The head features a row of seven 'chicken head' or ribbed control knobs on a black brushed-metal faceplate, including inputs for high/low gain, volume, and a multi-band EQ section. The 'Traynor' logo is prominently displayed in a stylized silver script on a black background on both units. Notable for its 'overbuilt' construction, this model is historically significant for its high power output for the era and its reliability. Condition-wise, the grille cloth on the cabinet shows some light sagging or dust accumulation, and the Tolex exhibits minor scuffing consistent with age and use. The chrome trim on the edges appears mostly intact. The presence of the original carrying handle on the head and the overall cleanliness of the faceplate suggest a well-maintained piece of vintage musical equipment, valued for its warm, tube-driven harmonic saturation.

I have examined the images of this Traynor Custom Special stack (YBA-3 head and matching cabinet). Based on the script logo style and faceplate layout, this unit dates to approximately 1970–1973. The aesthetic condition is excellent for its age; the 'chicken head' knobs appear original, and the Tolex shows only superficial wear. The minor sagging in the cabinet grille cloth is characteristic of the original material and does not detract significantly from the value. Market demand for vintage Traynor equipment has surged recently as collectors and players look for affordable alternatives to 'Plexi' Marshalls and Ampeg SVTs. These units are famously 'overbuilt' with heavy-duty Hammond transformers. While not as rare as some boutique brands, a complete 'stack' in this cosmetic condition is relatively difficult to find, as these were heavy workhorses often subjected to touring abuse. Value is driven by the matching nature of the head and cabinet. However, several factors cannot be verified via imagery: I cannot confirm the presence of original Philips or Mullard tubes, nor can I inspect the circuit for modifications or capacitor health. The speaker composition (often 4x12 or 8x10 configurations) likewise remains unverified. Full authentication and valuation would require an in-person tech inspection of the internal chassis for date codes and original solder joints, as well as a load test to verify power output. Documentation of recent servicing by a qualified technician would provide a premium to the stated value. As it stands, this is a clean, highly desirable piece of North American amplifier history.
