You can use a tape delay...
If you don't want tubes, use transistors for it...

use a length of garden hose with a pair of transducers on each end

Use, endless tape echo!

For mechanics the best mehanism is 8 track player from last century!!!!!!

Spring-loaded reverb tank. Parts Express has some in their latest flyer - about $20. It will take a single transistor to drive, and one to receive.

Yes... at 340m/s, you need 68 meters of garden hose for 0.2 sec. delay...

with some valves you could also have a great variable delay echo...

How about a 1024-stage BBD using tubes?

More seriously though, many studios used to use 'plate echo' devices - which have quite an OK 'sound', but they take up a LOT of space.
Essentially what you need is a large sheet of thin sheet metal - like 6x6 feet.

I'd agree, tape is the easiers & cheapest. Cassette not easy to modify, but an old 3-head reel-to-reel is a pretty much ready made echo unit.
