Special "Heritage" TANNOY hand built speakers crossovers PIO Paper in Oil DUBILIER

Firstly, apologies, we have many crossovers for sale, we sold over 1000 pairs so far, for many models, from under £200 to over £1000, from great new caps types, to PIO (Paper in Oil) vintage caps, hand made to top quality PCB types, so, if you are confused, please read this link.

We are the No 1 provider in the world of new Tannoy crossover solutions.

IMPORTANT ALLOW 1-2 APPROX WEEKS DESPATCH

LET ME KNOW YOUR MODEL, AFTER ORDERING. TELL US YOUR DRIVER & CABINET, WE DO THE REST.

Here we have a very fine pair of TANNOY crossovers, with a mixture of new and NOS (new old stock) best of both worlds, principally using New Old Stock PIO Paper in Oil Dubilier / Nitrogol capacitors, externally some paint-wise are mint, some are less mint, scratches etc, but all are NOS (New Old Stock), so paint condition varies, but fully tested. To produce a very most excellent warm vintage sound.

Specifically aimed for existing owners as an upgrade for 15 ohm Blacks, Silvers & Reds, also for 8 ohm Golds, HPD & K series 25xx 31xx 38xx who seek PIO crossovers, without messing with your own crosssovers

or if you have drivers without crossovers and need some.

We have followed the Tannoy circuit exactly (with errors corrected). Of course we can make whatever you need. ASK. Hand built, by ex MOD trained wireman, with point to point wiring, in an open format, made to offer the best possible top quality vintage sound.

THE SPECIFICATION

The HF section - where the capacitors are “in series”, so the sound actually flows through the them, this is where its important to have top grade PIO (Paper in Oil) capacitors, so we uses NOS (New Old Stock) top Military grade MPE Ltd, DUBILIER, Cornell, PLESSEY, TCC VISCONOL capacitors, “Nitrogol” oil & paper, full tested and wonderful, with quality vitreous enamel Welwyn W22 7 watt 30 ohm resistor.

The LF inductor – we use top quality JANTZEN 4mH inductor AIR CORE, 1.2mm wire [serious upgrade], (1.2mH if 8 ohm) a vast improvement on the iron core original.  We have used a new quality CLARITY ESA 18uF capacitor, given it’s a parallel part (ie: not a series part where the music flows), and if difficult to find suitable 18uF oil & paper caps, it’s a great & better solution.

Obviously the capacitors will be used at low voltage, and are NOS, not stressed, not used and not worn out, we have powered up slowing and conditioned each one for 24 hours, to ensure superb operation.

2) Input wires - included (2 wires, standard set up).  For bi-amp ASK ... FREE.

3) Output wires / 4 pin plugs. NOS tin plugs (requestor our own superior gold plate versions (standard).

About the new 4 pin gold plated plugs.

An immense amount of time and tooling cost has been involved.  These fit the old Tannoy tin plated sockets, they are good fit, they take up the slack in loose old sockets as the new pins are spring loaded.  Made with FR4 1.6mm pcb’s, heavy 1oz copper with thick gold plated (military / aircraft). The old plugs and sockets had a solid pin and the old socket was only slightly spring loaded. The new plugs, the pins we use are VERY HIGH quality, military / aircraft grade, nothing finer.

The 3kHz HF “notch” filter ... fitted as standard. Easy to clip a wire to disconnect. Also available without ... ASK .. BUT fitted as standard.

Tannoy “Silver” & “Reds” as they are known, had very simple but very good crossovers, and there was a “honk” at about 3kHz. Many customers replacing old “grey box” crossovers for Silver and Reds, got to like these extra 3kHz frequencies, so they can choose to “have them” or not.

Who are MainlyTannoy ?

We have been working with Tannoy products since 1973, PA, install churches, theatre etc. I have been in the electronics business for more than 30 years, making products for many well known companies, like Naim Audio, Snell, BBC, BT.  We have supplied more than 700 pairs crossovers to date, over 10 years. Almost all the published data has errors and we have all the values correct, getting support directly from Tannoy in Scotland themselves.

Common questions answered ?

Yes, our crossovers are the best available on Ebay, no doubt. Our lowest cost is £160 a pair, no wires, no 4 pin plugs .. IMPORTANT if you are comparing prices. We also offer all the way to fully plug and play, hard wired input wires, hard wired output wires with wonderful 4 pin plugs.
(When ordered, the 4 pin plugs are £28 each, £56 a pair alone !!).
Of course, any more questions welcome.

The only PLUG & PLAY.

We offer the only FULLY FINISHED “plug and play” crossovers on Ebay … complete with input wires and output cables with new very superior 4 pin Gold plugs. (If you order that version).
