I have a question about subset.

[hanami]

I'm learning a lot about Candlestick phones here. I got to study history from the model's number to the time it was made. I just want to say thank you all the time.

I'm learning on SUBSET these days. There are Sidetone, anti-Sidetone, and among them models like 634 and 534, and the wood ones are not organized in my head because I don't have knowledge about them. Can the wood subset used for the candle stick connect to the ones with magnets like 315H? I learned that something similar to the 295A can be used.

(Post-up: It was a question of whether models with dials, such as 50AL and 51AL, can connect.)

There are different basic types of subsets for either local battery service, or for central battery service.
Local battery means the power for your own transmitter is not extracted from the line, but must be supplied on site from batteries (often 2x 1.5 V = 3 V). To ring up the central office or the other party the magneto has to be cranked. The induction coil will have a low resistance in the path from the battery to the transmitter. This type of induction coil cannot be used with a more modern central battery system.
Practically all automated systems, using dials, are central battery (CB) systems, supplying the power for the subscriber's microphone from the office. In the past, manually (non dial) CB systems also existed. In this case, lifting the receiver would not give dial tone but connect the subscriber to a human operator doing the connection manually. For the subset and the induction coil used in it, this makes no difference.
Anti-sidetone means that the induction coil is wound in a way that will not let your own voice pass through to your own receiver, or only to a much lesser degree.
While anti-sidetone coils can be manufactured both for the LB and CB system, they broadly appeared at a time when CB service had become the more commonly used system. Hence later wooden subsets are more likely to be CB and anti-sidetone, while early ones more often are LB - sidetone. Again, the latter cannot be used on modern lines.

Thank you for your reply!
I followed the link to Ripple and looked at the book.It was easy to understand because there was a detailed description and picture of the bellbox.Candlestick phones can be attributed to a desk-type phone from a wooden wall phone.


The candlestick phone I have is a sidetone type, so it feels like I'm talking on the phone in a can. I think anti-sidetone sounds a little clearer, but it's just an imagination.
