|  Re: SID-card scheme?
Yerzmyey: I'd say the full picture (concerning the C116 vs. expansions) would probably look similar to a case where you'd use more than one external cartridges at the same time with a stock 48K Spectrum.
In fact, expanding the ram internally doesn't result in significant rise in power consumption (partly, because the old 16K ram chips are removed in this process, so you won't power any extra chips as a result). A C116 expanded internally to 64K can drive a SID card without any further conditions (no new power supply unit is needed). ...From the other hand, powering more external cards, like an external 64K memory expansion together with a SID card should result in high heat dissipation inside the computer (as also known from the Spectrum) and occassional drop-outs of supply current if the datassette is used (which is powered by the computer alas the single power supply... unlike cassette decks used together with the Spectrum).
...Thinking it over, this all still doesn't look like any real restriction for you as you already have a Plus/4 (way more robust than the C-116 and has 64K already -- no problems to use a SID card with) and you prefer TED tunes anyway  so you can use the '116 together with an external expansion module :D . But if you'll really want a C-116, 64K memory and a SID card together, that must be possible to do, too.
