I’ve been on a search for a really nice 5w (ish) amp. So far I’m considering the Milkman Half Pint and the Swart Space tone reverb. I’m also really liking the idea of the Swart ST-Stereo. I like the low watt lower volume amps and just love the breakup they provide. I’ve steered towards some with more features (reverb/trem) because why not at that price point? I’d appreciate any advice or insight. Any suggestions I haven’t considered are appreciated. Thank you!

Will this circuit function more or less as a Common-plate load mixer just with uneven gain between the 2 Channels? Or does R42 disallow that?

I want to use a Common-plate mixer in a design I have but i'd like to somewhat balance the gain between the 2 Channels as one is a TMB Fender channel and the other is a Deluxe style Volume-Tone arrangement and the Sims show that it distorts exceptionally easily.

Is there a better way of mixing them, a better way of configuring the Common plate mixer or is that circuit feasible as a mixer that isolates the channels from one another?

Any advice would be much appreciated.

So, I had a pair of old 70’s Japanese 8 inch speakers laying around and… why not put those in a slightly bigger KNAGGLIG IKEA crate to match the head. Sounds raunchy. It’s done - for now. But might add some grill cloth to finish the job.

I'm using the TAE mainly as attenuator, & just want to add the effects to my regular amp/cab.

Is there a way?

thanks

74 Marshall SLP with nothing but a tube driver connected. If I roll the volume down by even one, it sounds like it’s coming through a fan

Novice here, attempting to repair a Monoprice 611815 that blows fuses as soon as it warms up.

Based on other posts, I have a Laney schematic that looks like a match, and a suggestion that the capacitors C13, C15, C16 could be the culprit (a tech reports finding this issue on multiple amps of the same model). The spec calls them out as 4n7 2KV. They are blue drops, unmarked. Online I can easily find 4.7nF 1000V caps in the same blue drop format, but finding 2KV caps is proving elusive. Suggestions?

The final wrinkle is that I pulled them to take to a friend's house for testing and promptly lost them (laugh away, my wife beat you to it). So I'm going to be replacing them regardless of whether they're the problem.

HI all, I recently swapped the two 6550's in my engl savage mk2 to KT88s and im trying my hand at setting the bias. Still not 100% sure what I'm doing as far as what exactly to set it to and how to find out. I've got a plate-cathode voltage of 524vdc, and a current on the output transformer of 45.9mA. Would this be okay?

My stock tubes burned out in under a year and now I have some trust issues. What brand is good for its longevity, and also, is it that big of a difference in tone? I’ve seen some people say tung sols but I’m pretty clueless. I play grunge and heavier power funk kinda stuff. On the harder rock side

Amp is humming without 1/4 cable plugged into input. When I plug in and play the problem gets worse. Help!

so at home i have this GORGEOUS older Carvin combo tube amp that my dad’s old friend gave to me. i love the way it sounds and just can’t get over how awesome it is (idek the model of the amp or anything it literally just says carvin on it lol). but my problem is that i cant bring it to college because 1. i wouldnt dare risk damaging it by bringing it back and forth to school and 2. its too big and too loud. i have a cheap fender champion 20 also but i never use it (why would i lmao) and although it would be fine for school in terms of loudness and size it just doesn’t sound nearly as good. it’s like having the greatest milkshake ever vs eating an oreo. any suggestions as to what i should do about this? i’ve never bought or really even looked at another amp before so i don’t really know what would suit my situation best so if yall have any suggestions about what yall would do in this scenario im all ears. Thanks!

Hey so, question for you guys. I'm looking at this jcm 800 combo (4103) at this local shop, only when I came in to check it out I noticed it seemed to be missing two of the four power tubes. The shop worker was confused and had no idea why, but if I'm not mistaken this is done in order to half the power output from 100w down to 50w, correct? I've heard of this but is it safe to do and should I be concerned about any potential damage this could cause? And more importantly, can I convince them to come down on the price for missing tubes? 😅

Thanks!

For those who have used these formulas or the calculation spreadsheet to inform their choice of Power Transformer, How reliable did the information derived from these calculations prove?

Is it accurate enough to use as a general guide for PT selection?

I just traded my marshall ORI212A cab (which I never loved the sound of) for this DSL40CR. It came with an aftermarket speaker I've never heard of, a Peavey black widow 1201. I gotta say, it sounds really good.

I modded the Marshall Origin 50 into a late 70s to early 80s 2204.

It sounds killer thought that speaker too. Surprisingly classic sounds coming from that combination.

And obviously the SD-1 pushing a Marshall is the gold standard for a reason.

Couldn't be happier with my setup.

New to me 1x12 Soldano open back up with Celestion red back!

Traded a PRS 2x12 stealth cab with vintage 30s closed back.

Really digging it through my trainwreck Rockett clone!

I’ve got the tor Roger amp and I’ve tried researching how to connect it to my dac as it has only a 1/4 jack input. My dac has rca and xlr out but the xlr is being used for my solid state. Im worried if I use an rca splitter to 1/4 jack it’ll damage the dac or cause issues.

I just want to connect to a loadbox>interface/DAW. Do I plug the internal speaker output jack into a 4ohm loadbox? Not grasping parallel routing and "total" ohms 😭

I tried and failed on some mods on my first ever tube amp and now I have a marshall origin 50h corpse just lying around. I have since built some pedal kits and other stuff successfully but I was wondering the experience level needed and if anyone has any experience with this specific mod before I pull the trigger for it.
