Re: Dumble 183 BOM

I'll second what Ian suggested, basically starting from scratch. Even if you find a BOM I strongly recommend verifying each component on it for accuracy to avoid possibly having to pause the build waiting for a missed or incorrect component to come in. This requires basically the same effort as star...

Re: Princeton reverb micro power circuit

Here is another OT option. This OT works with either a 12AU7 (22k) or 12BH7 (11.5k). Pay attention to speaker impedance if changing between the two types of tubes.

MOJO1580

And here is a schematic of this OT in use.

Re: Help Needed Fitting an OT that Doesnt Fit - 5e3

Otherwise, you can probably deburr with a little piece of sandpaper, or manually twisting the next size bit in the hole. You can do this! I have a set of these (different brand but same. 82° countersink/deburring bit. One can literally deburr an entire chassis in a matter of minutes with one of the...

Re: My first experience with Mullard reissue 12AX7’s

I found out today that Amplified Parts are going to stiff me for the 12AX7 as they don’t accept returns on microphonic valves. I was a bit annoyed as I don’t recall asking to purchase a microphonic 12AX7. Yeah, I think I won’t be buying Mullard again. I don't buy ANY tubes from Amplified Parts any ...

Re: Trouble getting into the forum

To clarify I only closed the tabs with TAG, I left several others open that did reopen when I restarted Chrome. I think the key was to clean out not only cookies but anything cached pertaining to TAG.

Re: Trouble getting into the forum

BTW, this is what I'm seeing wrt missing graphics: Anybody else seeing this? Response is extremely slow too. I was seeing this too but the other day I completely cleared out TAG from my browser and it's been working great since. I'm using Android (Samsung tablet and phone) with Chrome browser. Here...

Re: Starting to populate the chassis....

Are you by any chance using a light bulb limiter?

You may have an out of spec transformer.

Re: Starting to populate the chassis....

I've been having a bunch of issues with the site too...

Looks like your heater voltages are a bit low. I like to measure the heaters on a 9 pin tube while in Standby using pins 4/5 to 9. 6.3 vac is ideal.

Re: Hiwatt Dr103 copy mains hum and how to reduce it?

Glad you got it sorted out.

All of my amps have some hiss when cranked up, I think it's normal. Some tubes have more hiss/noise than others, especially in V1 position.
