Nice set Sandy. I've had one of these for about 25 years, and they work fairly well. They are considered the Muntz of early radios since they are so simple in design. The integral speaker is very unique and one of the reason I like the set so much.
There are no resistors in the set except for the grid leak detector. This is the part on the right hand side of the board that looks like a fuse. You need to try different values until you get the best results for the detector tube you are using. (typically between 1 and 20 meg) There were adjustable ones made that had a little slider coming out one end that made tweaking it in very simple. You can still find grid leak resistors from places like Play Things of the Past, or ebay, or you can just use a modern rheostat.
The only thing that may give you tropuble are the interstage transformers as they sometimes go bad. These sets are relatively inexpensive so even if that is the case you should be able to get a parts set.
Here's a schematic (for what it's worth):

There are few battery eliminators as already mentioned if you don't want to build one of your own. Another one is the ARBE III.
Enjoy!
