Re: Poor mans SSS ~
Jelle, You replied to my post the other day on this thread regarding my question about the UP amp. I guess at the time it was not exactly the response i was looking for however my posting that followed was somewhat agressive and uncalled for and i do apologies for my for comments directed at you. Th...

Re: Poor mans SSS ~
Da Geezer, you pretty much nailed it in your previous post. Jelle, The presumption that i use the search function kind of ticked me off a little. I have spent hours using the search function in this forum on both Trainwreck and Dumble sections. I have built and modified amplifiers with very good res...

Re: Poor mans SSS ~
Speaking of Ultraphonix, Out of all the D style amps this is the one that appeals to me the most. I have a Bassman AB165 that would be a perfect platform to convert to one however i am struggling to find any substantial ( non cryptic) information or schematic for one of these babies. Is there anyone...

Re: want 2 Rok JM signature tone board layout
Gents, I have been following all JM Sig posts with interest as i do like the sound of this amp. The pre amp looks to be closer to that of a 124 classic configuration with some slight variations ( Mid boost, 4.7uf cathode caps). The shots i have seen of an actual JM sig do not have the .001uf cap acr...

Bob,
Looks like you have the 220/150k plate resistors on V2 the wrong way round?

Re: What OT for my Z-wreck build
Rooster, Since i started my Wreck build over a year ago i have made some changes, particularly the transformers. The PT i had made here in Melbourne and i spec'd it the same as the Rocket PT - 280-250-0-250-280v @ 300ma. Check out RJ's site. Choke now is a MM-10H-CH. The OT i orginally went with was...

Re: Rocket PT order
Ok, I have received the first PT to trial in my Rocket build. below are some pics for comparison. I Fitted this PT to my amp on Thursday and did a show with it last night with no problems at all. As wall voltages do vary, the manufacturer spec'd it to 243v primary as this is the average mains voltag...

Re: Rocket PT order
Tansformer Companies build PT's with the description " international spec voltage " which does cover most world conditions but not all. Some good quality manufacturers do offer true 220, 230 and 240v. What happens is that a 240v spec PT is made. The secondary HT values are correct but all other seco...

Rocket PT order
I am going to place an order for some Rocket spec power transformers for Australia/NZ conditions ( 240v - 50hz ). These will be indentical to the Heyboer and Pacific ones sold by other members on this forum manufactured for north American conditions. The only difference may be they wiring colour cod...

Re: Wreck/Rocket
Rich how is your wreck treating you It was a great looking build. Which choke did you use? Mark, Mine sounds fantastic! I could not have chosen a better amp to build that suits my taste. My cab is loaded with a Celestion blue 15w and a WGS Blackhawk 50w. I had a full band rehearsal the other night w...

Re: Dr ZWreck is basically an AC30 with a top notch Compressor
[quote="M Fowler"] I increased the choke DCR and mA from the Heyboer 158L we use in the Rocket. I used the HTS-159Q 7H 150mA/100DCR. Also the Hammond 159P gets close at 10H/125mA/155DCR[/quote] Mark, Just curious as to your choke selections for this amp. Both have lower H and DCR to the AC30 and Roc...

Re: What OT for my Z-wreck build
Tdale, I did a Z wreck build earlier this year and originally used a Toneslut "Experimenters" OT with the 4.3 and 5.2k primaries. It sounded pretty good but opted to go for the A470 Dynaclone from triodstore. The difference was night and day, The A470 is killer!!! If i was to build a Rocket/Z wreck ...

Re: NON-HRM Skyliner 50w
Greg, Nice work. I have been contemplating for a while now to do a 50w ODS build and i think your clip has pretty much sold me on that. I have been pouring over months of postings in this forum about discussions of 50w or 100w, high plate/low plate, OD values etc etc...... and have mapped out a buil...
