Vox parts supplier

[markrgv]

Hi all,

Have a friend who is doing up a couple of Vox amps and is after a few bits; reverb unit, etc.
Are there any good suppliers out there that can be recommended - with either Vox original or pattern parts.

Thanks for your help,
Mark.

I guess you should a little more precise about which parts you want to find if you want to get any help...

I can't think of a Vox that I ever owned that had a built in reverb . . . . . . . .

The AC30 was certainly available with a built-in reverb in the 1960s. The controls were built into a white back panel like those fitted to retro-fitted Top Boost models.

As a matter of fact, there were quite a few distinct models available, right up to the "Super Twin Normal With Reverb II" (head and two separate speaker cabinets*) at about £200 in 1965.

[* No, I've never seen one of those either, but I've seen both AC30 Normals and Top-Boosts with reverb on the back.]

As JN has pointed out, and from North Coast Music:



'The addition of reverb into many Fender amps placed additional pressure on Vox to include this feature into their amps. Since Fender incorporated the Hammond Accutronics style reverb circuit into their amps. one would think that Vox would follow their lead, but this was not to be the case.

Tom Jennings, the president of Vox, resented having to pay the $1 per amp licensing fee charged by Hammond Accutronics for the use of their patented reverb pan. Instead, he designed his own reverb pan, just barely skirting the patents on the Accutronics unit.

The reverb pan designed by JMI for the AC-30 Super Twin used two 1 volt output ACOS GR71 crystal phono cartridges for drive and receive transducers. A single delay spring was connected to the needle saddles of each cartridge.




'The earlier addition of the Top Boost controls to the main control panel left no room to add reverb controls. The reverb controls were fitted into upper the back panel, as formerly done with the Top Boost controls. See photos at left.

The best that one could say about the JMI reverb pan is it worked to a degree, but the tone and depth of the reverb was certainly lacking when compared to Fender amps of this era. Furthermore, this phono cartridge based reverb pan would easily slip into a howling acoustic feedback if the amp was played too loudly. Even worse, replacement phono cartridges for this reverb pan have been unavailable for many years.

Not all AC-30 Super Twin amp heads incorporate either or both of the Top Boost or JMI reverb circuits. Some AC-30 Super Twin heads have non top boosted "Treble" or "Normal" circuitry while others may be top boosted with the treble and bass controls installed either in the back or top control panel.'

Thanks for replies...

Didier: There were no specific parts (except one), just wanted to know if there was a good general supplier for Amplifier parts and bits, etc in the UK, that people on here would recommend.

Dave R: With regards to the reverb unit; I have a Vox AC15 amp which has a reverb unit built in (not original 60s era) and i understand several others do - though maybe this is only from the 90s on. It was for one of these such amps that a reverb unit was required for - as a straight replacement for a broken original.

So same again, didn't know if there is a supplier out there (UK) who specialises in such reverb units - be it Vox or pattern parts, but i imagine that someone on here would know of such a supplier. The only suppliers i have found so far on the net are all US based

So if anyone can provide info on suppliers,etc, it will still be much appreciated.

Mark.

Hi Mark,

I required a replacement reverb unit for a vox ac30ccx that I was selling. I phoned Vox and got a replacement unit for £30.00 including postage of
£5.00.

Best regards,
Baz.
