    Bump Anyone have any suggestions on a luthier?

    OT5PP Frequency Response

    Ended up switching the mids cap from .047 to .022 and that actually gave me a decent amount of the low end I felt like I was missing. (Actually put the .047 and .022 on a switch so I can go between them). May still revisit the output transformer in the future, but for anyone else feeling like...

    OT5PP Frequency Response

    Interesting. Is there an example circuit using 6AR5? Or, would the 6AR5 use the same plate voltage, cathode resistance, and screen resistance as the EF80? I’m not very good at figuring out load lines.

    OT5PP Frequency Response

    Since there aren't really any high primary impedance push pull output transformers I can find besides the OT5PP and the Hammond 125, it leads me to a question. Since transformers are really just ratio's would a 11.25k:4 be equivalent to a 22.5k:8 ohm? I am using an 8 ohm speaker/load box...

    OT5PP Frequency Response

    There are plenty of mic preamps that use low power push pull tubes into a transformer without suffering a lot of bass roll off. I’m going into a Suhr load box into a computer usually, so there isn’t a speaker mass to actually move. If tube mic preamps can deliver a flat line level signal, seems...

    OT5PP Frequency Response

    Anyone know if there is a published frequency response anywhere for the OT5PP transformer? Hammond publishes freq responses for their transformers, but I can't find one for the OT5PP (which I know isn't a hammond transformer). I'm wondering if a different output transformer could give me more...

    Tele with strat hard tail bridge and strat pickups possible? (Madcat)

    Title basically says it. I basically want a madcat, but don’t want to pay over 3k for a used reissue and dont want a cheap knockoff. Can I mod a stock fender tele? 2 questions: 1. Can I replace a Tele bridge with a hard tail strat bridge? If so, what hard tail bridge would match the screw...

    Drop-in One Tube Reverb

    Why the smaller grid leak instead of a 1M pot? I got it together and working. Reverb sounds good. Better than the 12DW7 (to me). Can hear the spring jump a bit now. Only problem is I have ground noise coming in somewhere now. Didn’t know if it could be something to do with the reverb driver...

    Drop-in One Tube Reverb

    Ah, got it. Thanks again! I've got the 12DW7 in there now with the 22k transformer. Sounds pretty good honestly, but would love to improve it further, so that why Im thinking about swapping for the ecl82 setup

    Drop-in One Tube Reverb

    Thanks so much tubeswell! That is really helpful. One more question (for now). You mention an 8-10K reverb transformer. I am presently using a Hammond P-T1750A which is 3.5 watt 22.8K:8. Are you saying to swap for something like P-T1750E (15 watt 8.5k:8)? The wattage rating is overkill but that...

    Drop-in One Tube Reverb

    Thanks tubeswell. I'd thought about trying a ECL82, but would it just drop in without making major changes? I'd have to connect the screen I assume, but other than that? Would the circuit shown in this thread be basically the same?

    Drop-in One Tube Reverb

    I ended up making a couple changes that I think really improved things (to my ears at least) 1. Switched from MOD 4AB3C1B to Belton/Accutronics 4AB3C1B. The Mod sounded very plate like as I mentioned above. Sort of a mass of sound without an attack/spring drip. The Belton/Accutronics sounds...

    Drop-in One Tube Reverb

    Thats just changing the dry/wet mix and not the character of the reverb though, right? So by increasing the mix resistor you get louder reverb, but not more "dwell" right?
  15. C

    Drop-in One Tube Reverb

    Ok, fair warning - you may be dealing with a dumbass (me). I had the pots wired backwards, so when I thought the dwell was at max it was at 0 lol. Sounds much drippier with that corrected. Still not ab763 good (to me) but serviceable
