Re: Steel String Singer #005 build

What did you do with the abandoned Erwin chassis please? If it is to be for sale I may be interested (also in EU).

Re: Cabinet questions

Yup. Personally I prefer the "baffle" closer to the front, but I think it's just to taste. Keep an eye on clearing the distance to the metal corners if you do bring it forward. Here are photos of one of mine - the metal is 20mm wide, baffle 18mm + grill cloth, and I ran the metal strip flush with th...

Re: Another SSS #002 build thread (Ryan/Erwin)

Thanks Matt, Glenn! I'm about to start a 2nd Gen ODS build with one of Erwin's chassis myself. Nice! I'd like to see that build too. I see Erwin only has one of those chassis left . Mmmm... One thing to check before you get too far along is clearance between the corner of the Reverb board and the XL...

Another SSS #002 build thread (Ryan/Erwin)

Finally got round to starting a build using the bag of bits I bought from a member here. I feel extremely lucky to have another of these chassis which aren't available now. SSS #2 is of course documented thoroughly but maybe others, like me, enjoy watching build threads :) Day 1: hardware and pre. h...

Re: Cabinet questions

Hi James

I’m not sure I completely understand the question, but I’ve built all mine with the front of the chassis 3/4” (20mm) back from the grill cloth, and the chassis about 1/4” (3-5mm) set back from the cutout. The grill cloth I set at around 5-8mm back from the cabinet front.

Re: Steel String Singer #005 build

I'm looking for anchor nuts to use in my build and as I used the same dimensions as your #004 chassis I just now realize that I can't seem to find any anchor nuts that fit (looking to order from Aircraft Spruce in Germany)? Fusion says the holes are .578 in apart. I originally used these in my Ryan...

Re: Steel String Singer#002 build from Scratch

What did you do with your mid switch please? I’ve tried various things people have suggested but never been satisfied.

Re: Looking for AmpNation JM Chassis

I've PM'ed but will reply here too in case there is someone else who really wants one.

I have 2 in Denmark, Europe.

I don't have immediate plans for them, so would sell one (maybe both) for the actual cost price - i.e. including the import duty I paid - if it helps someone.

Re: PTFE Hookup wire - stranding?

Excellent you’ve saved me asking my follow up question too.

Unless someone chimes in with a different PTFE wire recommendation altogether I’ll go with that, and those strippers.

Thank you very much

PTFE Hookup wire - stranding?

Hi folks Having used solid core pushback all my life, I'm about to invest in some reels of PTFE stranded hookup wire and have a newbie question. From what I gather, 22AWG is what we want for the signal wiring and in the EU the Alpha 5855 (600v Silver plate copper) looks like a reasonable option on 1...

Re: Starting to populate the chassis....

You’re adjusting the bias until you read around 47mV across your 1ohm resistors? Sounds correct. The b+ will change a bit as you adjust bias. It’s an iterative process. What the bias voltage from the potentiometer is (-48V or whatever) isn’t so important. Tubes vary, plus your 1ohm resistors will al...
