Re: Dumble ODS #22
I agree this amp sounds fantastic. Regarding the presence pot and mid switch...maybe a similar arrangement to #093 but with the pot mounted externally rather than a trimmer on the board. srvdumbonetb2.jpg P.s. I am not sure why the filename for this picture, but afaik it has no connection to SRV. -...

Re: AN Wonderland/JM 100w layout
Hi everyone, Starting my second build after a Marshall Plexi 18W that came great. I have a Twin Reverb 65 RI chasis with PT and Reverb Transformer. with a late 70's Ultralinear OT that I'm planning to use without the UL taps. The twin comes with an extra 12()7 tube. I was wondering if I should use ...

Re: New F&T 100uf 350v caps: Tip Of The Week
In an ac100, I tested the following F&Ts at the mains: - 100uf 550v axial (special series for Frag Jan zuerst): fast, explosive response, good harmonics - 2x 220uf 350v A series axial in series: slower, laxer. less aggressive and bold All caps were slow-formed (voltage dropped to 2v across 100k res...

Re: Peak Boomer Nonsense incoming
This could actually be an Overdrive Special with the HRM controls on the front. Actually wait it has 4 preamp tubes so maybe something different. Its also running a Hammond 1760 series output transformer. The power transformer looks like a Hammond 372HX. I am judging this by the look of the height d...

Re: New F&T 100uf 350v caps: Tip Of The Week
I have used these 2 different series of Nichicon caps for 50 watt and 100 watt D-Style builds and they are noticeably tighter sounding than the F&T caps. If you enjoy the bouncy F&T these maybe too tight for you. I used these for the first 2 caps for the Power Supply. 2Rock is now also using these (...

Re: I bought a solid walnut apartment. Uh, speaker cabinet.
This cabinet came out nicely. Sounds great, with a Celestion G12H and Eminence Wheelhouse 150. IMG_2876.jpeg IMG_2877.jpeg Congrats Christian! Looks amazing in the room. I love mixing Eminence Hemp speakers with Celestion G12 speakers. I recently did a 2x12 with a Cannabis Rex and a Celestion G1265...

Re: New F&T 100uf 350v caps: Tip Of The Week
Someone correct me if I am wrong, but if that brand or any brand for that matter reduced the physical size of its filters while still using the same type of dielectric material then when a amps power supply is pushed to the point of sag then there's going to be ghost notes showing up and a lesser a...

Re: New F&T 100uf 350v caps
Are fakes a problem with F&T's? I didnt hear about fakes but who knows these days. I think that Mersen who bought F&T is making them smaller so that they can fit into more customers electronic components and thus more sales. Maybe making them smaller has caused this issue with them reading smaller ...

New F&T 100uf 350v caps: Tip Of The Week
I recently purchased a handful of F&T and IC 100 uf 350v caps from a well known European reseller. I guess ever since F&T got sold the new owner is making their caps half the size of the old 100uf 350v caps. This was the first thing I noticed. When I went to measure them all the F&T caps most of the...

Re: CF driver Va - Vk voltages in SSS consensus?
Thanks for posting these pics ElectronAvalanche. Especially this one here! The famous 68k resistor feeding the reverb circuit from V1 to V2 (seen on far right of the pic below). Dumble must have been very found of doing his reverb like this. The fact that builders like 2 Rock now use this in several...

Re: ODS gutshot from Pinterest
These look amazing Bas! I believe we can also laser the black powder coating to put our own branding on these. Maybe a diode or fiber laser will do the job. As I mentioned the boards worked great for me. I wonder why Dumble stopped using them? Maybe he had issues with the guy who was fabricating the...
