Guitar Tube Amp From Scratch Part 1
canada goose clearance sale Guitar amps are really pretty forgiving to build. There are plenty of ways to do it wrong, but those ways are rarely self destructive, Canada Goose Coats On Sale just Canada Goose online kinda crappy sounding. Figure out the crap, change it. That’s the great thing about point to point valve amps: Canada Goose Outlet they’re easy to fiddle with. canada goose clearance sale
buy canada goose jacket This is canada goose going to be the first in a series on Building a Guitar Tube Amp From Scratch. The series will demonstrate the creation of a guitar amp from a random set of transformers. buy canada goose jacket
canada goose store I’ve been volunteering at a recycling/reusing facility that takes donations canada goose uk outlet of appliances (computers in particular), refurbishes and remixes them, then sells them. The facility pursues the noble goal of providing computers and internet access to people who otherwise wouldn’t be able to afford them. cheap canada goose uk Exhibit A: three transformers taken uk canada goose from a tube amp of some sort. When reusing parts there are three useful circumstances to take note canada goose uk black friday of: canada goose store
canadian goose jacket I: Model numbers of the amp you are dismantling: canadian goose jacket
Canada Goose Jackets A: This lets you look up schematics. Just about any tube amp is halfway to being a guitar amp; usually fiddling with the gain structure will get you something musical so the chassis, sockets, and components can canadian goose jacket be reused. Canada Goose Jackets
cheap Canada Goose B: In this case the amp had at some point made someone feel sad and impulsive, so most of the chassis was no longer usable or recognizable. cheap Canada Goose
II: Model number on the transformers:
A: Lacking a schematic, one can always search for the transformers. The internet is just one big pile canada goose coats on sale of information. And cat pictures. Even a scan of an eighty year old electronics catalog could have the info canadagooseoutlete you need. Why is there a scan of an eighty year old electronics catalog online? Who knows? It’s the internet.
Canada Goose Outlet B: My Google fu was no match for this iron. No matter: I have one final refuge. Canada Goose Outlet
canada goose deals III: What valves the chassis was populated with. This lets you know: canada goose deals
Canada Goose Parka A: Roughly how many watts the Output Transformer can handle Canada Goose Parka
Canada Goose online B: How much heater current the Power Transformer can supply Canada Goose online
Canada Goose sale C: Roughly how much high voltage (B ) the Power Transformer cheap Canada Goose can supply. Different configurations and biases will use up different amounts of current, but this should get you quite close. On Hi Fis the Choke Canada Goose Parka will likely be able to handle whatever B the Power Transformer can dish, but not always. For our little demonstration the Choke will be canada goose factory sale downstream of the output stage, so if they came from the same amp the Choke should be hardy enough. Canada Goose sale
canada goose coats on sale D: It can get complicated. Ask questions and check out some of the great forums and libraries available online. Keep in canada goose clearance sale mind Canada Goose sale that buy canada goose jacket all forums have search functions. canada goose coats on sale
buy canada goose jacket cheap E: I’m not trying to scare you. So I need to find their datasheets and add up their current draw. buy canada goose jacket cheap
canada goose black friday sale Most commercial amps use all available amperage, so the current the existing valves drew is all you can expect canada goose store to use. Adding up the valves tells me that I have 2.1A at 6.3v for heater current and about 77mA for the B . Note that the datasheets tend to list the B at idle, or when there is no sound to amplify. This simplifies things kind of like how high school physics formulas are excempt from gravity but it’ll get us in the area. If another tube is substituted, just make sure the valve has an equal or lower idle rating. If all else fails; power the thing up and keep a finger on the power transformer. canada goose black friday sale
canada goose coats If the wires on the transformer lack any distinctive coloring, it would be handy to create labels. This can be as goose outlet simple as stripes of color using markers or folded tape with numbers. canada goose coats
Using the ohm meter, test all the canada goose coats possible combinations of wires to see what connects to Canada Goose Jackets what. Usually the reading will be very low, as a high DC resistance is rarely desirable in a transformer. Draw out the canada goose black friday sale connections and make note of the resistances.
canada goose clearance On the output transformer I found four separate windings: uk canada goose outlet two with two connecting wires each and buy canada goose jacket cheap two more that each had a center tap. canada goose clearance
canada goose For example: The yellow wire was 17.6 Ohms away canada goose clearance from the red wire, but 8.8 Ohms away from the canada goose uk shop red/yellow. I checked the resistance between the red/yellow wire and the red (8.8 Ohms) and confirmed that the red/yellow Canada Goose Online wire was directly in the middle of the red and yellow wires canada goose.
