    8" vs 4" Speakers for practice amp

    I just went thru this last year - I have a THR10 but while it's good I never really bonded with the sound. I found an old PEAVEY Blazer (Rage with a small reverb) that had an 8" speaker and it is AWESOME for low volume practice. Something about the low vol and the 8" is really nice. NOT as...

    Current Tayda fees after new tariff?

    yeah still only expensive shipping options - would definitely be ordering more stuff if it went back to the old rates. not that tayda part costs are not GREAT - but I hate paying $20-$30 US for shipping a few parts.

    source for knobs WITHOUT indicator?

    yeah I actually found the Strymon knobs and they're pretty close to perfect - not sure of the exact diameters (Im looking for about 15mm) since I dont own anything from them. But yeah, expensive. Not as bad as Mouser, DigiKey, Newark - which dont have much either.

    thanks - I'll take a look

    source for knobs WITHOUT indicator?

    looking for some encoder knobs - ideally aluminum, black, but have to be without "indicator" - D shaft would be perfect but I can adapt to 1/4 or 6mm these seem to be surprisingly HARD to find. ideally something like this but no top or side indicator...

    low gain germanium 2N1304 - worth anything?

    I think that or a slight variation is what I used before. I built it again and I'll test to see how close. BTW how long do you wait for these to stabilize? The general consensus is "till it settles but dont wait too long". 1 min? 5 min? I know they're handling sensitive etc

    low gain germanium 2N1304 - worth anything?

    I need to redo both if Im going to actually sell I guess. Did it looong time ago. Whats the best circuit values for that?

    low gain germanium 2N1304 - worth anything?

    Thanks yeah I've seen prices and stuff on ebay and I guess I could go that route - just didnt know if they were real prices or 'wish' prices due to demand.

    low gain germanium 2N1304 - worth anything?

    I inherited a bunch of these 2N1304 - tried to measure them as best I could - see pics. Worth anything to try to sell on ebay or somewhere or not worth the hassle? Made a few fuzzes with the ones 2N1306/7 that were higher gain now theses are just gathering dust. Also have a bunch of 1N994...

    encoders? for Boss pedals

    Thanks - dont think those have the "push switch" like the TIME knob needs - think thats the other 2 pins in the pic from that I measure its supposed to be a 11mm, 20 detents, 17mm shaft (7 busing/7 flat) the tayda seems exact except a 'tad' shorter 15mm shaft, 7 bushing 6 flat so it sits 1mm...

    encoders? for Boss pedals

    I figure you all might have some experience or know someone.... Anyone know a source for part number and or parts for Boss pedals? Specifically I have a RV-500 with a bent TIME encoder and need to replace it. Not worth sending it in ext for a fix. It really looks like this at Tayda is very...

    Resistors 100R and 47R

    I always thought the "R" was used instead of a decimal "." like 4R7 would be 4.7 ohms (hard to see that decimal). Same as 2K7 would be 2.7K ohms

    Power Supply

    expensive but the CIOKS SOL or DC7 (I have a SOL) are great. I've looked at the DC voltage of a lot of cheaper power suppies and they either A) dont regulate well or B) have "spikes" from the components (PWM supplies). Some people swear by "linear" regulated supplies but those are hugely...

    Reverb Preferences

    little late to reply but yes I researched this extensively before I did my board for "surfybear" and this came up. Yep, seems the schematic for the mosfet resistor value is wrong, as such much more current will flow and the resistor needs to be higher wattage. Also the mosfets definitely...

    Real Spring Fet Reverb (Surfybear)

    BTW - here's a really simple spring reverb circuit (you could probably add controls for dwell etc) from an old PEAVEY amp. Uses a higher impedance tank for their teeny little tank but you can use a better nice sounding tank like a MOD 8EB2C1B Reverb Tank 800/2200 ohms. You'd want to redesign...

    Real Spring Fet Reverb (Surfybear)

    This was going to be the housing etc "concept" lol. The green glowing "spring" is just for looks. The RCA jacks go to the tank.

    Real Spring Fet Reverb (Surfybear)

    The RV3 trimpot is supposed to be adjusted so the TP1 (testpoint) is 6V. This site https://bulinskipedals.com/shop/fet-spring-driver-reverb-diy-pcb/ used to sell PCBs and has a schematic, parts list, and writeup. This is the CORRECTED schematic of mine and PCB

    Real Spring Fet Reverb (Surfybear)

    I did a PCB for this ijn KICAD and never got time to finish. I have a project file of the one I made prototypes for (with some errors) and a never one with the errors (I think fixed). If anyone wants the files etc your welcome to it. The below is my version 1 with errors - I stupidly had a...

    adding fx loop to old peavey amp?

    yeah good point I do need to take it apart and prove it. although the clean channel (which is what I mainly use) only goes thru a few and I normally run this very "clean" hence the desire for a pedal FX

    adding fx loop to old peavey amp?

    Sorry if a bit of off topic - but FX loops are a big thing with using my pedals I build. Was thinking of messing around with one of my old SS amps - good old Peavey Blazer. Was wondering if anyone would be able to give me advice on where I could add an FX loop? I looked at some of the other...
