The one in the picture I posted is Xicon. I think the MF may indicate metallic film or something like that. The Xicon are a bit bright so maybe they are not the HAD approved caps. I believe AE is Arco.

Re: DUMBLE Trade Mark
Did I read that correctly, you want to punch the guy who has been handling Dumble's estate in the face? Maybe time to take some meds and spew your bs somewhere else.

Re: High-plate Classic
Looks great Ian. I live close to Ian and have heard the amp, It sounds great. The only thing you may want to look at is the output transformer secondaries. You are riding right against them with your power tube grid wires. You usually want to keep those away from other signal wires or try to cross a...

Re: New 183 build
Are there any dumble amps built 100% from scratch? I'm not aware of any, but that's my limited experience. All Dumbleland/SSS/ODS/ODSR that I am aware of were built 100% from scratch. I've now seen multiple ODS that were built in a fender chassis, not from scratch no? He gutted them, and rebuilt, o...

Re: R.G. Keen ne-2 bulb transformer test
Thanks RG. Yeah I guess I probably should have stated that the mains voltage were I live is usually at 118vac so I’m pretty close to the 117vac that most blackface Fenders back plate say they run at. Although that brings up a question, where the mains back in the 60s ever actually 117vac or did Fend...

Re: New 183 build
Yeah, to say a guy who was building PAs and designing amps for Mosrite when he was a teenager is cutting and pasting is a bit much.

Re: R.G. Keen ne-2 bulb transformer test
Thanks again for the responses. Martin, the transformer gets slightly warm with no loads, warm approaching hot with the filaments connected, and hot sitting idle with everything connected. I have a Pro Reverb of the same year and even with a tube rectifier and both tubes sitting right behind the tra...

Re: R.G. Keen ne-2 bulb transformer test
Thanks guys. Yeah, not so black and white a test. I was playing around with the Twin and Pro transformers to get a feel for what to expect. However, the main reason was to test a power transformer in a blackface Bandmaster that I have been working on for a bit and would like to use regularly. The tr...

R.G. Keen ne-2 bulb transformer test
So I have been playing around with this test for shorted transformer windings using a ne-2 bulb and a low voltage power supply ( 6v lantern battery) and although it seemed pretty black and white, there may be some grey areas. I am using a Mercury Magnetics Pro Reverb power transformer(known to be go...

Re: New 183 build
In #183 he painted the black paint or nail polish on the power tube grid resistors but why? I see it sometimes on the solder joints in the ac sections of some of his amps but I still can’t figure out why he did that and it seems random as to wether he does it or not.

Re: Missed Robben Ford and 102 last night in SoCal
I watched the video. Sounds like a couple of the tunes could be through the Super. Robben was born in Woodlake which is up north in the San Joaquin valley.
