8 ohm resistors for making dummy loads, the 100w rating is assuming they are on a heatsink of some sort. I used one recovered from a scrap PA amp, but just attaching them to a metal chassis seems sort of standard. I like fins and stuff on my heatsinks though. I'll probably list some heatsinks eventually as I work through the pile of stuff in my workshop. Can chain them up following same impedance rules as speakers to have different ratings of dummy load, bear in mind the amp rating is not maximum output, they tend to put out more when pushed to distortion, so better having headroom, and have headroom on that for safety. 4ohm and 16ohm ones in other listing to give options.

Body is 60mm long, 90mm overall with connectors. Base is 21mm wide, 15mm tall.

Use add to basket function if want multiple different items and want an accurate total.

Overseas bidders check in advance about postage. If you find it last minute and bid, that's cool, but message and and give me time to check postage before paying, so I can actually find out and invoice correctly.
