Not in the L15-25D series I'm afraid. But I'd use the 63V trafo for L25D, 2x250/8. I'd used such a combo for my Magnepan LRS for a while until I built L15D 2x300/4, but I had to put down the 63V trafo and get back to an old SMPS 300R.Actually, I have two of them but I would like to have 2 mono subs (each with passive radiator). There are some reasons for that, especially ambient ones and acoustic as well...
I will built 2 pieces simmilar to this, I already have all the drivers and just need 2 mono amps for them:

So, are there any other D-class modules which will be happy with weak 4 Ohm load and +/- 63V DC PSU?

actually. Low power MOSFET. For example, irfi4019 is better than IRFB or industrial MOSFET in effect.
You mean l15dx2. There is no problem with this.Can the TIP41C on the L15D board be replaced by a TIP31C ?
But the l15d uses 2sd669. It cannot use TIP41
I have built two mono amps with l30d, l20 was not capable of driving under 8 ohms loads! My power supply is a thoroidal trasfo plus 6 -10.000mf caps. They have burned down in one of the amps. I m told such power PCB class d, requires a lot of current, so l must substitute for a 2000 watts power switching module. Is it true? What item on Ali express do you recommend??!I see I have another option: L30D. Its power is even stated on 2 Ohms so it wont have problem with mine 3,1Ohm
There will be some surplus of power but I think it wont be a problem - I wont take them to the extremes. It will be still just house listening.
L15d is a dip component. L15dsmd is an element of SMD.ljm_ljm, what is the last version of your L15d amplifier (also L15D smd)? I saw ver.6 on AliExpress store. Is this true?
These are two different versions. There should be no fakes in l15d or l15dsmd. They are blue.

What do you mean. Your power supply is broken, isn't it.I have built two mono amps with l30d, l20 was not capable of driving under 8 ohms loads!

Do you have any pictures. Let me see.
I do not recommend switching power supply. The switching power supply has a high probability of damage.
And there are almost no examples of damage to the ring transformer.
I know about smd and dip versions. Actually I got SMD boards and I like them. I want to buy dip version too. Here is two pictures, what is yours?L15d is a dip component. L15dsmd is an element of SMD.

The caps have burned down, l30d, l have been suggested a 2000 watts switching power supply, all class D power amps have switching power supplies, without any problem. How can l Repair it?What do you mean. Your power supply is broken, isn't it.

OK。 Dip version l15d is the same as your photo.I know about smd and dip versions. Actually I got SMD boards and I like them. I want to buy dip version too. Here is two pictures, what is yours?
The difference is that in the early days, it was a single-layer PCB. Now it is a double-layer PCB. It is the one on the right of the picture.
They are all fine. But now there is only one on the right. Double layer PCB version.
Your L30D is a black radiator. I bought it about three years ago.The caps have burned down, l30d, l have been suggested a 2000 watts switching power supply, all class D power amps have switching power supplies, without any problem. How can l Repair it?
Is the capacitor damaged.? You mean the capacitor? It's bulging? Note that there are many fake capacitors on the market. A lot. Be careful.
If only the capacitor is damaged. Then you need to buy a brand new one. Genuine capacitor. Just replace it. Watch out for fakes.
The capacitor needs to use 100V withstand voltage

What do you mean? I bought an L 30 D all parts soldered!! PCB is screen printed Jim_jim (!) --- who assembled it then (?) It s a fake(?) What is a fake ? The red cap? I had installed a former L 30 d before , and that red cap exploded !!!! Boom really. Who makes this damn Jim Jim ????Your L30D is a black radiator. I bought it about three years ago.

I wonder who designs and assembles these L 15 - L 20 L30. (?) Jim_jim who is it? Precise: another L30 d had exploded. Knock !!!! Vera. Loud. Exploded the red cap you see in the picture! Also dangerous. I don't know how I managed to get a new one from the usual Chinese on duty. With what I spent, in total I bought two class D amplifiers, Behringer A 800, I have three currently and they are fine. So should I throw away two very good toroids? Poles, buy the two new switching power supply (?) Etc etc etc better not to be lost in such chinoiserie at the showdown.What do you mean? I bought an L 30 D all parts soldered!!

Red capacitor? What exactly is it.
I suggest you send an email to your supplier.
It is better to have a clear picture. Tell them where the damage is.
If the time is short, they will give you free components. Of course, if it is more than 2 years old, it may need to be purchased again.

The current l15d is about this.I cannot see a SONGLE relay on either if these photos. My (your) L15D Pro boards have them.
Maybe the photos taken in different periods will be slightly different.
But generally speaking. We will use better components or PCBs instead of earlier versions.
Maybe the capacitor will be different. This is related to the procurement time.
In addition, if you have l15dsmd, you can always use it. It does not need to be replaced with l15d.
They have the same effect.
