Also I checked the coil like Mr Jaun said and it seems to match a data sheet I found



You cannot view this attachment.


What's weird about the data sheet is I downloaded two pages and I can access and read them etc plain as day but if I try to upload them here they get dim and won't let me do it  :grr

Yes sir thanks definitely better doing it that way if I connect it at voltage I get a click

You cannot view this attachment.

If I adjust the power supply "com" and "NC" open at about 16v DC then I have to roll it back to about 6v DC before it closes back up

You cannot view this attachment.

Also if I hold the relay while doing that if I don't hear it I can feel it

It might be more obvious without adjusting supply while testing.  Just set for 24VDC and turn on. 
Some are not very loud, put your finger on it and you might feel the click.

Well I tested one of these new relays with a power supply and some leads and a multimeter monitoring continuity.

They seemed to open and close fair enough but I'll be damned if I heard a single click  :grr

Idk maybe it's not supposed to make an audible click

But...I think that's what I am hearing click in the power supply as voltage is increased.

Comparing the markings on the devices I definitely see a difference but idk if that means anything.

Oh well it's not like I spent a fortune 🔮 on these.

1/4 or 1/2 watt in carbon film or metal film will be fine.
Check the dimensions, some of the modern parts are so tiny they can be difficult to work with in applications like this.

I will order those resistors 330 ohm & 4.7k ohm. Schematics don't say, but what type of resistor should I be using "Carbon Film" or "Metal Film". Also what watts should I order those resistors in? The attached picture shows where these resistors have been mounted on another amp and I will do the same to mine.

330 ohm shows mounted on R29,R30
4.7k ohm shows mounted over D5

Hi everyone,

I'm currently working on a personal solid-state amp project, and I'm drawing inspiration from some of the classic transistor amps I've always admired. In particular, I'm looking for the complete schematics of the following models:

Randall RH200 G2 / RH100 , etc

Peavey XXL Transtube

I already have the power amp sections, but what I really need now are the full schematics, especially the preamplifier sections, which are key to capturing the character and tone I'm aiming for in my build.

If anyone has access to these schematics or can point me in the right direction, I'd really appreciate it. I'm also open to sharing schematics or technical info in exchange if that helps.

Thanks a lot in advance! :dbtu:
Raul

How about resistance?
