The symbols weren't Letraset although the rub down technology is the same. Alfac is the brand I remember and I think Seno was another. You can get an idea here.
However, you don't need PCBs to use transistors, nor do you need the metal working skills demanded by 'chassis bashing' for valve radios. Stripboard, like Veroboard, with copper strips punched at 0.1" intervals, was ideal for transistor circuitry. The only special tool you needed was a spot face cutter to remove the strip around a hole to make a break in the track - or you could use a suitable size twist drill bit or even drill right through the board, but the tool was easier and neater.

One of the advantages of Veroboard for the beginner was, if you used transistors with the common e-b-c pin out, you could virtually transfer the printed design directly to the board, which could take up a fair bit of room but you would soon learn how to adapt the layout to save space like this.
Of course, the 0.1" graph paper was ideal for planning layouts with its 1:1 scaling.
You could soon find that, with a bit of careful thought, and most, if not all, of the components mounted vertically, that you could achieve very dense population densities.
