Re: Benson Monarch

I changed the Split plate back to 10k/100k and it's definitely louder now, but I'm still not loving the output. I'm going to go back and look things over. Oh, and I forgot my decimal on the Reverb, it was .83V, not 83V. I did switch to 100K on the Reverb plate. It matches the newer guts shots of the...

I read through the tread, so this is what everyone has with this build? 2. No ground loop buzz, but some amp hiss. I'm assuming it's due to the fact the...

Re: Benson Monarch

Reverb transformer is not used in this design. It has a 12DW7 CF stage that feeds an ~800 ohm Z tank. Most of the reading is related to quirks that needed ironing out per particular build and correct component values. But I think this project is worthy of the read, as many have appeared to have suc...
