Vox AC30 website updates

April 2026

28th April

A Univox guarantee card from 1958. On the other side, various notes, and a short section on the guarantee of valves: 90 days from date of purchase, any faulty item to be returned to the valve manufacturer, preferably through the dealer from whom the Univox had been purchased. 90 days was the length of time given also on early Jennings amplifier guarantee cards (expressed as "three months").

Section (h) - on the front of the card (below) - indicates that the guarantee of the Univox as a whole would be void "If any parts or components have been substituted for those fitted, or where the instrument has been used with any other makes of valves than those specified by the Jennings Organ Company".

The makes used for the Univox by Jennings were Brimar and Mullard.

Added to the page on accordions with Jennings shop plaques, the Hohner "Double Ray" pictured below.

27th April

The Who, March 1965, apparently defaulting on the return of a Vox Piano Bass and Phantom guitar and case. Catalogues and pricelists aside, references to the Piano Bass are few and far between - see this page.

In view of "Phampton", the handwriting likely to be that of the case clerk.

26th April

There is now a page on a superb late Univox J6 currently in Australia - serial number 3642. Thanks to Glen for the pictures. The main Univox index page is here. More to come shortly.

25th April

Entries have been created/updated for six AC30 Super Twins with serial numbers in the range 2500-3000: 2503, 2556, 2573, 2591, 2791, and 2941.

24th April

The page on early AC30 Super Twins, late 1961 to early 1964, has been updated - principally to include entries for amps that had already been referenced on other pages.

In terms of balance of production, the busiest period was evidently early on, dropping off considerably during the course 1963. There are almost as many amps with serial numbers in the 5000s as there are in the range 6000-10000.

23rd April

Added - about time - to the page on AC30 Super Twins in 1964, a detail from the JMI pricelist from February of that year offering for the first time amplifier sections on their own. Hard to say for sure, but it may be that relatively few were sold in this way. Contemporary photos of bands seldom show in this respect anything other than full Super Twin sets (amp and speaker cabinet).

February 1964.

22nd April

Normally seen with a later Continental with a sloping lid, below a small detail of Manfred Mann with an early one, square lid, music stand on top.

The "Vox Continental" logo was introduced by JMI some six or so months after the music stand had been phased out.

20th April

Entries created for seven AC30 Twins with serial numbers in the 18000s - 18277T, 18640T, 18642T, 18740TB, 18780TB, 18855T, and 18894T. "TAY", one of JMI's finishers, signed in chalk the cabinet baffle of five of these amps - signing off either the finishing of the baffle itself, or perhaps the installation of the speakers. Her signature generally appears between the two T1088s.

16th April

Just a couple of updates in the 19000s - pictures for 19283 and 19410, cabinet and serial number plate only in the case of the former. The chassis and speakers currently in the cabinet were evidently introduced later, the assemblage as we have it probably dating from the 1970s/1980s.

Examples of these post-JMI and post-VSEL bits-and-pieces AC30s with Expanded Frequency copper panel chassis will be gathered together on a page of their own in due course.

15th April

On the page for Twins with serial numbers in the 20000s, entries for 20042TB, 20136TB, 20183TB, 20612TB, 20713TB, and 20868TB have been created/updated.

14th April

There is now an entry for AC30 Twin serial number 20797 on this page. Thanks to David for pictures and info. Further Twins with numbers in the 20000s to be added shortly.

AC30 serial number 20797.

12th April

An entry has now been added for AC4 serial number 3997, thanks to Darren for the pictures. There is also an entry now for AC30 serial number 7442B, thanks to Nick.

11th April

Entries created/updated for eleven AC30 Twins with serial numbers in the 21000s: 21007, 21200, 21270, 21330, 21377, 21620, 21632, 21690, 21773, 21807, and 21994.

10th April

6th April

An entry coming shortly for AC30 Twin serial number 7442B. Thanks to Nick for the pictures.

2nd April

Published by the National Accordion Organisation, to which Tom belonged, eight issues of its quarterly "Accordion Digest" magazine. The earliest full-page Jennings adverts (known so far at any rate) were placed in these.

Below, a member's badge, and small silver and gold medals. These last were awarded during the country-wide heats leading up to the grand finale: "National Accordion Day", normally held in November. In company with Selmer and others, Jennings sponsored a cup for the winners or runners-up in various chosen categories (i.e. not the same ones every year). Tom occasionally presented the cup himself, along with the medals and awards to the other contestants in the heat.
