Annual Leave August 2026

IMPORTANT

  • UK CUSTOMERS - Prices exclude VAT (20%) which is only shown in check-out.
  • OVERSEAS CUSTOMERS - UK VAT disappears when you enter your country in check-out. Purchases from outside the UK will NOT pay UK VAT.
  • Instead of flooding you with a huge selection, I have tried to keep shipping options simple and straight-forward.
  • To save you a little money, items under 100.00 GBP may be sent without tracking.
  • If you're outside the UK, your purchases may be subject to import duties (tariffs) which I'm afraid, can be unpredictable.
  • After purchase, you'll want to go to 'Shopping Cart'. Please enter a valid e-mail address and then press <Enter> on your keyboard to bring up shipping options and delivery address entry option. You can still cancel your purchase if you wish.

USA FlagIMPORTANT - US TARIFFS 2025

On 29th August 2025, the 800 USD de minimis exemption was abolished. All imports from the UK into the US are now subject to a 10% tariff.

I used to have a single shipping price category for US and Canada. After 29th August 2025, that changed and shipping to US and Canada were separated. The increased shipping price to the US is due to me including US tariffs in the shipping cost (DDP, or delivered duty paid). YOU DO NOT PAY ANYTHING MORE WHEN YOU RECEIVE YOUR ITEMS.


EU FlagIMPORTANT - EU IMORT FEES 2026

On 1st July 2026, the €150 customs duty exemption was abolished. All goods from the UK to the EU are now subject to import fees. This will apply to each item declared and NOT the value of the entire shipment.

I used to have a single shipping price category for Europe. After 1st July 2026, that changed and shipping to Europe (EU) and Europe (non-EU) were separated. Each EU state has its own rate of VAT and duty and I'm afraid small businesses like Plasma Music Limited simply cannot keep up.

UPDATE - 8th August 2026

As of 12th August 2026, exporters to the EU and Norway will be required to register for EPR or 'Extended Producer Responsibility'. Registration is required for each member state. There is a cost involved.

To comply with the new legislation is quite impractical for a small business like Plasma Music. I have there fore made the sad decision not to offer my products and services from the EU and Norway.

If you have any questions about my on-line store or the products and services I offer, please take a quick look at my FAQs and of course, you can always just contact me.

MARSHALL JMP-1 STUFF - Putting all my bits 'n' pieces for the Marshall JMP-1 into one place will hopefully make things a little easier for fans of this legendary MIDI valve pre-amp.

SIMMONS SDS7 HEAVEN - Back in eighties, I was part of the Simmons team based in St. Albans, Hertfordshire, England. A couple of years ago, I made the decision to get reengaged with my Simmons past and developed several peripherals for a few of those classic instruments. As it turned out, I designed a lot of bits 'n' pieces for the Simmons SDS7 specifically, so many in fact, that I decided to give the SDS7 its own category in my online store.

PML-TX01 Transformer for the Marshall JMP-1
Product Details

The PML-TX01 isn't just a replacement transformer for the Marshall JMP-1. An upgraded design, this drop-in device features laminates made from a material that's been specifically selected for reduced oscillation, thereby reducing hum and heat generated.

Made in the same factory as the original, the PML-TX01 is pin-for-pin compatible with the Marshall (Dagnall) TXMA-00014 transformer, so it's pretty straight-forward swapping out the old one.

Fully detailed, illustrated and printable installation instructions are available after purchase. If you miss the link, please don't hesitate to contact me and I'll send them out to you.


MARSHALL JMP-1 VOLTAGE SELECTION

I regularly receive two questions from those interested in my PML-TX01. Both are about the Marshall JMP-1 input voltage selection:

  1. Is the PML-TX01 replacement transformer for the Marshall JMP-1, 230V or 115V?
  2. Are the voltage selector components diodes, ferrite beads or just fancy wire links?

The answer to the first question is, just like the original TXMA-00014, my PML-TX01 has two separate primary windings, each rated at 115V. So…

  • EUOPEAN / UK VOLTAGE SELECTION. Wired in series, the primary becomes a single 230V winding which is suitable for 220V (Europe) and 240V (UK, Australia). To wire in series, connect ONLY LK2.
  • USA / CANADA / JAPAN VOLTAGE SELECTION. Wired in parallel, the primary becomes a single 115V winding suitable for 120V (USA and Canada), 100V (Japan). To wire in parallel, connect LK1 and LK3.

It's quite easy to implement 240V to 120V conversion, or 120V to 240V, for example. Those eighties style wire links can make things look complicated but the original links were JUST WIRE LINKS and nothing else, so you can use wire. I would however, recommend that you use covered wire as these connections carry mains voltage!

The image below shows the transformer windings. On the left are the two primaries which connect to domestic A.C. power. Jumpers LK1 and LK3 are installed for 115V operation. For 230V operation, ONLY LK2 is installed.

It's important that the input voltage selection is chosen properly so below things are drawn that may be more representative of what you might actual see in your JMP-1.


A WORD ON SHIPPING COSTS

Annoyingly, my shopping cart software displays shipping information after you’ve confirmed your payment option. I’m trying to get this changed as I believe that customers should always know exactly what they’re paying. Of course, I have no control over import duties but I try my best to give clear, concise information.

I therefore maintain a ‘Shipping Prices’ page and visitors to my website who are interested in buying stuff, have the opportunity to check shipping costs to their country / region.

My shipping costs are calculated on item value and not weight as everything is insured.

UPDATE - August 2023

I'm offering my CR2032 adapter for the JMP-1 at a discounted price when purchased with the PML-TX01. Hey, you gotta take the board anyway, right?
