I would think the 'recording out' is just some 10K-1M Resistor in Series with the Output load. So if the Output Load Resistance (no speaker present) is very High then there will be a Voltage Divider present, thus the low signal The amp has a shorting speaker jack, so that with nothing plugged in, t...

Ok i found this. https://reverb.com/item/8189-carl-s-custom-guitars-8-ohm-speaker-soak-guitar-amp-power-tube-volume-attenuator Pretty good price so gonna just buy it. Didn't find any power resistors laying around or at work. -------- One thing to note however is that it says 50W max. Seeing that my ...

Ok thanks i will try this. It will be interesting to see if this helps with my 'recording out' level? I think it might be related because before even seeing a schematic, I would think the 'recording out' is just some 10K-1M Resistor in Series with the Output load. So if the Output Load Resistance (n...

You should get plenty of recording signal out of that Jack if the master volume is opened up enough, get yourself two 8 ohm 25 watt resistors, wire them in parallel to a 1/4" inch Jack and unplug the amps speakers and plug in the resistor load, then you should get tons of recording signal level! Yi...

Currently I have nothing connected to the amp speaker output. (Is this ok, and can I remove the output tubes if not using?) No that's absolutely not ok, any signal will put significant stress on the power tubes. Unfortunately the recording out won't work without power tubes in place. So your saying...

How much signal are you pumping into it from the external gear, if it's more than 350mv, than yes you will clip the preamp section dependant on how strong the preamp tube is for the channel you are playing thru. If the amp was running thru its own outout stage and speakers it will only take a input...

I am using the 'head only' in my recording setup to run my bass and guitars through and use the Recording Output What's the 'recording output'? What is connected to the amp speaker output? The schematic has Vdc and Vac noted, so if your rig set up is ok it may be a good idea to compare measurements...

Hi all, I have an old Fender Bassman 10 my friend gave me that was sitting under the stairs of an old house they cleaned out. The cabinet had some awful toxic smell that I unfortunately could not get rid of so I stripped the head and speakers for a new cab. Seeing that a custom cabinet was around $3...
