Je mets en vente mon RAT SubZero Blues Junior.
L’ampli est un clone chinois de blues jr qui a été considérablement amélioré par la boutique RAT (liste de toutes les modifications détaillées sur le site de la boutique: http://ratvalveamps.com/subzero-tube-20r)
Liste des principales améliorations:
- Câblage refait, changement de composants.
- Ajout de l’OPR (power scaling): un « master » global qui permet de profiter du crunch du blues junior (master et gain à 100%) tout en jouant à volume tout à fait décent.
- Auto-bias.
- Tous les condensateurs de tonalité ont été remplacés par des orange drop.
- Ajout d'un standby
L'ancien propriétaire a fait la demande à RAT d'ajouter un footswitch pour la reverb (qui sonne plutôt très bien !) . Il y'a également un footswitch pour le boost.
L'ampli prend particulièrement bien les pédales d'effet.
Je fournis le manuel qui décrit toutes les modifications effectuées.
Nouveau prix: 400e.
Remise en main propre uniquement, pas d'envoi.
Liste des modifications:
1. - 'OPR' - Output Power Reduction (Power Scaling).
2. - The Amp is completely Stripped and then rebuilt, making sure that all fasteners are Tight or Thread-Locked as required.
4. - The HT Voltage (B+) is Spot-On but the Heater Voltage is WAY Too High - I have corrected that problem and the Heaters now run at 6.3vac, as they Should.
5. - I have done Several Modifications to the Power Supply - Increased the Smoothing Capacity for 'Tighter Bass' - Fitted a 'Safety' Resistor so that the Amp can Not hold a Lethal Charge when switched off - All of the Main Power Supply Resistors have been replaced with 'Wire Wound' or 'Metal Film' Components.
6. - All of the 'Tone' Capacitors have been replaced with 'Orange Drop' Parts. This gives the Amp much better definition. The Tone Controls Sweep from 'Zero-to-Max' on each Frequency.
7. - Full Lead Dress - All Transformer and Heater wires in a Valve Amp must be tightly twisted or they will induce 'Noise' into the Amp Circuit. Twisting all of the wires and placing them in the correct location does make this Amp quieter (No Background Noise - Buzz+Hum).
8. - The Standard Input socket is a Problem. It is PCB Mounted and made from 'Hard' plastic. The first time you 'trip-up' over your Guitar lead, you will destroy the input socket. It is then a Major job to replace the socket as the Amplifiers PCB must be removed. The Socket has been replaced with a Quality part that can be easily changed in about 5 minutes (if you ever need to change it).
9. - The Stock Amp is not Fitted with HT and Heater Fuses - It is Now.
10. - Preamp and PI Heaters Converted to 'DC' - The 2x Power Valve Heaters are 'AC'. This Stops any Hum and Buzz and also allows any Make of Valves to be used in the Amp.
11. - The Amp has been converted to 'Auto-Bias' - Class A/B. You will NEVER need to Re-Bias the Valves. Output is 15 Watts RMS - 22.5 Watts Peak Power.
12. - Boost Footswitch in Metal Housing with 3m Lead. A 'RED' LED Illuminates when the 'Boost' (Fender 'FAT') Circuit is Active.
13. -Full RAT User Manual detailing all of the Modifications.
14. - All Amps are 'PAT' Approved.
