Wellgood amp enclosure

 

Thinking of getting on but am wondering what users in the US have done for an enclosure? The round shape was made to fit into 20mm electrical trunking junction boxes that are available in Europe.? Could save me some time if anyone has it figured out. Thanks

I went on e-bay (UK etc) and found I could find folks selling those perfect round enclosures in bags of 5 or 10. Cost for each was $3 to $4 but shipping was about $25. But in the end it still was a deal. I ended up with 10 for less than $6.50/ea.

can you not find the dimensions online and make some using a 3d printer? Just a though

Suggestion for KISS method completely DIY.? I thought it was rather difficult to make such a small PCB preamp DIY without a special PCB, so I am just using a 80x80x50mm waterproof electrical box with a LZ1AQ preamp constructed bug style on some double sided PCB 60x60mm.. The new box will be fixed by bolting it through the old potting compound of a blown Wellbrook loop given to me by a friend, after making new end connections.

Thanks for all the suggestions, but I recently purchased an LZ1AQ type amp from Everett instead.? Local waterproof PVC electrical boxes fit the circuit board just right.? I use 1/2 inch Heliax for the loop material.? Little bit of modification and all is well.
 

Diecast aluminum boxes are relatively inexpensive, some can offer waterproofing with an inset gasket, and offer good E-field shielding (if proper attention is paid to ingress/egress of conductors).?

My first question on the 3-D printed enclosure would be survival to solar UV radiation.

There is a filament known as ASA that is really durable and offers much more UV resistance but it requires a printer that can handle hotter melting temps and has a heated bed.? I have some but have not tried it out yet. Normal PLA barely works but I found it does not hold up well outside here in the Midwest UV and rain, plus it breaks and cracks easy.

If anyone is interested, I have several retrofit amps for the Wellbrook ALA1530 loop. They are in a PVC case, and potted. They are a match and fit perfectly on the ALA1530.?
